How we keep GitHub fast
Reminds me of <a href="http://www.codinghorror.com/blog/2011/06/performance-is-a-feature.html" rel="nofollow">http://www.codinghorror.com/blog/2011/06/performance-is-a-fe...</a> :<p>"The simple act of putting a render time in the upper right hand corner of every page we serve forced us to fix all our performance regressions and omissions. [...]<p>Most of the performance fixes were trivial, and even the ones that were not turned into fantastic opportunities to rearchitect and make things simpler and faster for all of our users."<p>Stackexchange open sourced their profiler at <a href="http://miniprofiler.com/" rel="nofollow">http://miniprofiler.com/</a> (.NET & Ruby)<p>The post provides some data showing how they improved their site performance over time where Github just states they have a strategy to use "powerful internal tools that expose and explain performance metrics". Guess it's just common sense now.
