5 If using Linux, you need a kernel with epoll. Sure, libevent will
|
|
|
6 work with normal select, but it sucks.

8 epoll isn't in Linux 2.4 yet, but there's a backport at:

|
12 You want the epoll-lt patch (level-triggered).

|
14 If you're using MacOS, you'll want libevent 1.1 or higher to deal with
|
|
|
15 a kqueue bug.

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)
