““I would send out some contests. “Here's some code. Here's the benchmark. Make it fast.” I sent our load balancer's header parsing. We were all writing crazy regexps that didn't backtrack and tried to capture things with the most efficient capture groups. And we were all competing, getting faster and faster and faster. Then one guy comes over the next day. He had written it all in C++ with XS, and so he was like, “I win.””
