Even the distilled code is maybe a wee bit long for here, so I made a gist: https://gist.github.com/3252353
I wanted to try doing non-blocking I/O and a reactor event loop. The gist is an excerpt to simplify the problem case. What I left out is the fun stuff where Racket could make this less painful, such as using continuations or simply generators to avoid nested-callback-chain heck. But before the fun stuff, the foundation: Under a light load everything works fine. But ApacheBench with -c > 2 is making it unhappy, as described in the comments. Sometimes it will blow through 10,000 reqs at -c 20 with no problem. And giving at least 2X better reqs/sec than comparable thread-per-connection example. Yay! But on most runs it's getting errors with "input port closed". And rarely I will get a channel? from sync when it should only be an eof-object? or integer. And rarely I even get a Racket seg fault. Boo! So. Probably I'm doing one or more really stupid things? Any advice would be welcome -- thank you! ____________________ Racket Users list: http://lists.racket-lang.org/users
