I'm using imapd-2002d on CentOS 3.4 (binary equivalent to RH ES 3) This is my home server on a box with 640MB RAM, of which 540 MB is consistently disk cache.
I am running apache 2.0.46 and squirrelmail 1.4 to provide webmail service, and what I'm finding is that when I connect to the server there are significant delays in opening my mail folders. As I've investigated, I see that when imapd starts the system is in iowait state for quite a while. In this case, quite a while can be 30-60 seconds. Since the overall load average on the box averages ~0.5-0.8, and so much of the RAM is cache, I'm stumped as to why there seems to be so much io going on. My mail folders are mbox format on an ext3 partition. The main mail folder (file) is about 200M. What can I do to increase performance? (I operate under the assumption that since I'm addicted to email that my mail file is included in the dick cache.) I'd appreciate any advice that can be provided. Thanks in advance!
