I've tried libevent:

web server( a simple skeleton):
http://aoclife.ddo.jp:8080/dIIgS0n6
source code:
http://aoclife.ddo.jp/~vuhung/foss/libevent_http.c

ab benchmark against libevent_http: 197 req/sec
ab benchmark against httpd 2.2.3: 157 req/sec

I have not tested libev but it sounds better than libevent:
