A Look At Microsoft's 'Mini Internet' For Testing IE

Posted by Soulskill on Friday February 17, 2012 @05:19AM from the a-series-of-tiny-tubes dept.

MrSeb writes "With the grandiose bluster that only an aging juggernaut can pull off, Microsoft has detailed the Internet Explorer Performance Lab and its extraordinary efforts to ensure IE9 is competitive and IE10 is the fastest browser in the world. Here are a few bullet points: 128 test computers, 20,000 tests per day, over 850 metrics analyzed, 480GB of runtime data per day, and a granularity of just 100 nanoseconds. The data is reported to 11 server-class (16-core, 16GB of RAM) computers, and the data is stored on a 24-core, 64GB SQL server. The 'mini internet' has content servers, DNS servers, and network emulators (to model various different latencies, throughputs, packet loss)."

They wanted to account for any kind of lag, so by having it all in house and disconnected from even their internal network, they have control over all variables so everything is equal.
They did this post on their blog yesterday http://blogs.msdn.com/b/b8/

No, it means that Windows has a 100ns granularity on it's timestamps.
