The Real Mobile Performance Problem
This morning I ran a speed test using my iPhone tethered to my MacBook Air (via Bluetooth). I was not so much interested in the actual download speed (which I found to be pretty impressive using a 2 1/2 year old iPhone), but more in the latency numbers.
Here are the results – the top test is using my iMac to access http://speedtest.comcast.net Notice that the latency is sub 10 ms (great) and that my location used a server in Centennial CO (about 10 miles away). Overall I have no complaints at all on the desktop
The second test is the MacBookAir test via an iPhone. Note the latency – almost 1/2 a second. Also notice the server. Using my IP address it guessed that the closest test server was in AR.
