Things to consider when optimizing at the 99th percentile. Variance is key and is one of the biggest reasons EBS blows.

Context Needed

Whenever I see calls-to-action like this, I think about engineering school: someone at probably every school reminds every young engineer that if they cheat they'll likely kill people. The stakes are rarely so dramatic in web operations but that's no excuse to slack off.
