| 1 Dependencies: | |

| 3 -- libevent, http://www.monkey.org/~provos/libevent/ (libevent-dev) | |

| 5 If using Linux, you need a kernel with epoll. Sure, libevent will | |
| 6 work with normal select, but it sucks. | |
| 7 | |
| 8 epoll isn't in Linux 2.4 yet, but there's a backport at: | |
| 9 | |
| 10 http://www.xmailserver.org/linux-patches/nio-improve.html | |
| 11 | |
| 12 You want the epoll-lt patch (level-triggered). | |
| 13 | |
| 14 If you're using MacOS, you'll want libevent 1.1 or higher to deal with | |
| 15 a kqueue bug. | |
| 16 | |
| 17 Also, be warned that the -k (mlockall) option to memcached might be | |
| 18 dangerous when using a large cache. Just make sure the memcached machines | |
| 19 don't swap. memcached does non-blocking network I/O, but not disk. (it | |
| 20 should never go to disk, or you've lost the whole point of it) | |
