He didn't benchmark it against nginx. Per the linked presentation, all he actually benchmarked it against was mongrel and lighty w/fastcgi for php.

Its amusing how often slashdot summaries are wrong and no one reads the original article...
the actual quote is:
"It is faster than all(?) other web application frameworks for serving small dynamic webpages. Please let me know if you have a case where another framework is faster!"
Not once does he say it is faster than nginx or anything of the sort, just a bad summary and away people go with it.
Not fair, you didn't tell me you're going for a world record when you tossed your "little webserver" project so casually in IRC.
I guess tis the season for beating nginx in Lisp ;-)
