It Appears AT&T Wins the Download War

Posted by Jeff Campbell in "Apple iPhone, iPod Touch, iPad" @ 05:30 AM

http://www.edibleapple.com/2011/11/...t=Google+Reader

"People seem to have a love-hate relationship with AT&T. On one hand, people love to bitch and moan about the crappy reception they have with Ma Bell, yet there was curiously no exodus of subscribers when the iPhone came to Verizon and subsequently Sprint."

Perhaps Verizon doesn't care since they are focusing on their 4G network? Whatever the reason, it appears from the charta above that AT&T does indeed have the fastest network speed when compared to Verizon and Sprint. I thought it was rather weird they found that voice quality when Sprint iPhone user was calling was best and when AT&T iPhone user was listening they had better quality. Answering calls use AT&T, making calls use Sprint?

iPhone 4S Speed Test, Real World Style

Posted by Jeff Campbell in "Apple iPhone, iPod Touch, iPad" @ 04:00 AM

http://reviews.cnet.com/8301-19512_...subj=News-Apple

"Cool as she is, the iPhone 4S' new personal assistant Siri hasn't been able to tell me in a meaningful way which iPhone 4S offers the fastest data speeds. In the end, I resorted to the usual do-it-yourself approach: a real-world test. And the results were interesting."

No shocker it isn't as fast as a 4G phone, and even though he says that you should avoid the 4S if you have a 4, he does so based on the speed or lack thereof. I think that it is worth an upgrade if you want the better camera and Siri. Speed never really was a consideration in my thinking, what are your thoughts?

Speed of iPhone 4 Versus iPhone 4S on Video

Posted by Jeff Campbell in "Apple iPhone, iPod Touch, iPad" @ 03:00 AM

http://www.cultofmac.com/123848/iph...st-fight-video/

"This isn't the best way of showing the speed increases that come along with the iPhone 4S, but it is one of the ways that the iPhone 4S' faster A5 chip will immediately be felt: in significantly shorter app launch times."

It might not be the best way, but seeing it side by side does make the point.

AT&T Apparently Has a Different Definition of Unlimited Than the Rest of Us

Posted by Jeff Campbell in "The Competition" @ 01:00 AM

http://allthingsd.com/20110729/atts...ting-throttled/

"So much for AT&T's grandfathered unlimited data plans.Confirming a report in 9to5Mac yesterday, the carrier said Friday that it will soon throttle its heaviest data users as part of an effort to alleviate congestion on its network."

Starting October 1st, if you hit the magic top 5% of data users, your speed will be throttled back until the next billing cycle, as a punishment for being a data hog, even if you are on the unlimited plan. If I was an unlimited user and they did this, I certainly wouldn't be happy about it. I guess you still can get all the data you want, but it would be at a slower speed. I would like to know what "extraordinary usage" is defined as by AT&T though, as that is the trigger point to get to the top 5%. It is certainly a worthless phrase if I can't quantify it, but they say they will give you a heads up before it happens so you can adjust usage during a grace period. What are your thoughts on this change by AT&T?

What SSD Do You Have?

Posted by Jeff Campbell in "Apple Laptops" @ 02:30 PM

http://www.zdnet.com/blog/apple/201...The+Apple+Core)

"Several months ago, MacRumors noticed that Apple was using two different suppliers for the Solid State Drives (SSDs) in its MacBook Air models - Samsung and Toshiba. At the time Samsung SSDs benchmarked significantly faster (both in read and write speeds) than the Toshiba SSDs."

I don't think it would matter too much which SSD you have, except for the variation in the speed benchmarks. The disparity isn't just a few MB/s either. Using a 128GB Samsung the test resulted in 246 MB/s write and 264 MB/s read speeds in the 11-inch MBA. However on the 13-inch MBA, using the 128GB Toshiba, they only got 156 MB/s write and 208 MB/s read speeds. Quite a difference. If I were to get one of the slower ones, I'd be tempted to take it back for one with the Samsung in it. You can find out which one you have by going to About Mac -> More Info -> System Report -> and click on the Hardware. Then go to the Serial-ATA section and if the APPLE SSD is followed by SM you have the Samsung. If you have a TS however, you are stuck with the Toshiba. What are your thoughts on the debacle, or is the speed difference really that big of a deal?

iPhones Battle It Out in Chicago

Posted by Michael Knutson in "Apple iPhone, iPod Touch, iPad" @ 01:30 AM

http://arstechnica.com/apple/review...to-the-test.ars

"The Verizon version of the iPhone 4 doesn't need a full review-partially because you've read a bunch already, and partially because there's not a lot to differentiate it from the AT&T iPhone 4. Yes, iFixit found a number of subtle differences between the two devices on the inside, but from the user end, there are really only two major differentiators: choice of network and the personal hotspot feature.

We decided to focus our testing energy on these two differentiators, plus the Verizon iPhone's battery performance, with a special focus on Chicago."

It should come as no big surprise that AT&T's network is faster for data, with AT&T's HSDPA able to theoretically do 14Mbps downloads, while Verizon's CDMA EVDO Rev A offers a theoretical maximum of 3Mbps downloads.

Performance testing showed: AT&T winning every Latency test; SpeedTest Download and Upload speeds had varied download winners; while AT&T was faster in every upload test; downloading Angry Birds (free) at 15.1 mb was always faster on AT&T; but a YouTube video of 4:35 (m:ss)  download was nearly the same on both networks. The review does offer a probable explanation for Verizon's YouTube performance: their optimization and buffering of video stream content.

Finally, they do caution that where you use your iPhone (and the carrier service at that location) will always trump any benchmarks, so, balance AT&T's performance against Verizon's strengths: phone calls, and the mobile hotspot feature.

How Does Your ISP Stack Up?

Posted by Jeff Campbell in "Apple Talk" @ 04:00 AM

http://techblog.netflix.com/2011/01...p-networks.html

"As we continue to stream more and more great movies and TV shows, we find ourselves in the unique position of having insight into the performance of hundreds of millions of long duration, high-definition video streams delivered over the Internet."

Unfortunately my ISP (CenturyLink aka Embarq) doesn't stack up very well, but I do live in a rural area of the state so the fact that I even have broadband at all via DSL is amazing to me. I used to use Hughes Satellite for my broadband service, even though it was horribly slower than what I have now it was still better than dialup. So does anyone else think this might be just a little poke towards the providers in this war of net neutrality? Then again, Comcast is right up at the top so not sure how bad they feel about this being posted, in fact I would think it would give them some bragging rights to get more sales.

Busting Bandwidth Bugaboos: Troubleshooting ISP Speed Problems

Posted by Jason Dunn in "Digital Home Talk" @ 11:30 AM

Since most Thoughts Media readers are using high-speed Internet, I decided this article would benefit everyone, so it's one of our rare across-the-network pieces of content. I hope you find it useful!

Figure 1: What is this, 1994 all over again?

Whenever bandwidth is discussed, there's always lots of finger pointing because there are so many variables, and players involved, that it's rarely a simple issue. My particular bandwidth bugaboo this morning? I was ticked off that Dropbox (referral) was only uploading at 10 KB/s. I left a 900 MB transfer running all night and it wasn't finished in the morning, and that's when I discovered the awful speed. My first instinct was to point a finger at Dropbox, thinking there was some sort of bandwidth throttling going on. I did a speed test with a tool my ISP provides (speedtest.shaw.ca) and was shocked to see 1.7 Mbps downloads and 107 kbps uploads (Figure 1). It's normally 20x that on downloads and 10x that on uploads, so I knew something was wrong beyond just Dropbox. Read more...

AT&T Says "It's Not Our Fault" Regarding Slow Upload Speeds

Posted by Jeff Campbell in "Apple iPhone, iPod Touch, iPad" @ 03:30 PM

http://www.engadget.com/2010/07/07/...prit-fix-in-th/

"As we'd suspected, AT&T isn't intentionally limiting upload speeds on iPhone 4s in some markets where things suddenly got slow over the weekend. Or that's the company's claim, anyhow -- and seeing how they're actually calling out a supplier in the process, we tend to buy it."

They posted some info on their facebook page as well, basically saying that it was caused Alcatel-Lucent equipment and only affected about 2% of their customer base, or as the press release says "...those using Laptop Connect and smartphone customers using 3G HSUPA-capable wireless devices in markets with Alcatel-Lucent equipment."

AT&T, FTW!

Posted by Jeff Campbell in "Apple iPhone & iPod Touch" @ 10:00 AM

http://www.pcworld.com/article/1895...mance_test.html

"After generating disappointing results in our tests last spring, AT&T's 3G network is now the top performer in our 13-city tests, with download speeds 67 percent faster than its competitors."

It appears their work on the network has paid off, at least in the 13 cities that were tested. Interesting that New York City had speeds three times faster than last spring and San Francisco's speed was up by 40% from the same time in 2009.

So AT&T Does Have Fast 3G Afterall

Posted by Jeff Campbell in "Apple iPhone & iPod Touch" @ 07:00 AM

http://www.macworld.com/article/144...l_mwnws_h_crawl

"Although AT&T has been taking a pounding lately from Verizon ads and from customer satisfaction surveys, a new study suggests that the carrier can take solace in the fact that its 3G wireless network is the fastest in the nation."

The study from a company called Root Wireless, shows that in the areas where AT&T has 3G, the speeds are faster than any other major U.S. carrier. The tests were done in Chicago, Dallas, Los Angeles, New York, Seattle, San Francisco and Washington, D.C. The key point is that you need to be in a metropolitan area to even get the 3G speeds, so that is still a problem, one that Verizon has been pointing out regularly in their ads. But it is nice to know that, if you get in a 3G area, you will get a speedy connection if you are on AT&T, reassuring right?

2009 MacBook Air Slower Than 2008 Version

Posted by Jeff Campbell in "Apple Laptops" @ 12:00 PM

http://www.9to5mac.com/macbook-air-slower

"Ouch. Those numbers below have to hurt if you are in the market for a new high end MacBook Air. Macworld tested the new machines and found the high end 2.13GHz MacBook Air didn't perform as well as the previous high end 1.86Ghz machine with the same 128GB SSD. In fact, to them, it was noticably slower."

Makes me wonder, since I'm thinking of getting another MacBook, if the 13 inch MacBook Pro isn't the way to go. It is only about 1.5 pounds heaver with bigger hard drive and faster processor, as well as built in superdrive. I've done some weight comparisons (very non-science, lifting one then the other) in the Apple Store, and the difference wasn't all that much. But I sure like the thin factor of the Air. What would you buy if you were in the market for a laptop and having a built in superdrive wasn't a deciding factor?

The S Stands for Speed!

Posted by Vincent Ferrari in "Apple iPhone & iPod Touch" @ 11:00 AM

http://www.appleinsider.com/article...eed_report.html

"In releasing its new speed-centric update to the iPhone, Apple has boasted that the 3GS is twice as fast as its predecessor, but the company has remained mum on the handset’s actual specifications. Thanks to T-Mobile of the Netherlands, though, we know with certainty that the 3GS sports a 600MHz processor and 256MB of RAM – this compared to the 400MHz processor and 128MB of RAM on the iPhone 3G. Based on the report released Wednesday from Medialets, a smartphone-based advertising and analytics platform, the iPhone 3GS spec bump far exceeds Apple’s “twice as fast” sales pitch in real-world tests."

That fourth bar is the 3GS (head over to the link below to see the full piece and a larger version of the graph). For my day to day iPhone usage, the speed bump is more than noticeable; it's downright huge. I noticed it most when I was demoing the Push Notifications of BeeJive two nights ago. Launching, closing, getting a notification, and relaunching the app took nowhere near as long as launching the app used to take on the 3G.

Another place I've noticed the speed difference is in Safari. Pages load much faster and tap to zoom and pinch are much faster. Obviously, I can't quantify my results, but luckily lots of people have done that for me already.

CNET Says Safari 4.0 Really Is Mad Fast

Posted by Vincent Ferrari in "Apple Software (OS X)" @ 11:00 AM

http://crave.cnet.co.uk/software/0,...49301219,00.htm

"We determined on a PC that Safari was a whopping 42 times faster than Internet Explorer 7, just over six times faster than Internet Explorer 8, 3.5 times faster than Firefox 3, and 1.2 times faster than Google Chrome... On Mac OS X, Safari was four times faster than Firefox 3 and a depressing (for Opera) 7.5 times faster than Opera 9."

Safari 4.0 is pretty darned fast. I've been very impressed with it since I started using it. In fact, it's my default browser both on Mac OS and in Windows. I know some people have reported stability issues, but I haven't had anything of the sort. What made me make it my default browser was the speed, and frankly once you get past the really long startup time (it does take longer than Firefox or IE to startup) it's just blazing fast.
