I'm aware of it (you forgot to mention that kqueue is on the OS X as well). So what?

There are probably hordes of people who will be willing to run Mongrel2 on *BSD platforms, precisely because of the performance reasons. And Zed is a famous tinkerer rather than a religious zealot, so very probably he could be interested in checking kqueue as well.

"Why not" is also a good reason for a hacker when he's lacking other reasons.

My point was that comparing something that only runs on Linux against something that only runs on (various) BSDs adds a lot of other noise to the comparison - it's no longer the same hardware, install, and tuning, with just a different kernel call.

I see your point. Still it would be useful to see some typical BSD/kqueue in action compared to typical Linux/*poll. I bet Zed is not doing a big sysctl tuning at this stage. Just leaving default system settings as they are still is some starting point for further investigations.
