Yeah, why would two pages be allocated per connection if there is no network traffic going on? It would be fun if somebody tracked down that overhead and reduced it. Once you write up your findings, you might want to post a question about that on lkml. C1000K / C1M in the subject line might get some attention :-) _______________________________________________ Libevent-users mailing list Libevent-users@monkey.org http://monkeymail.org/mailman/listinfo/libevent-users
