Increase the softlimit (double it) and tune mysql. I have servers with twice that load that run loads of around 10, but then again if you're running this on a P3 that will be a bit of a load. Also tune tcpserver by turning off some un-needed options. - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.

Re: [qmailtoaster] Benchmarking POP3
Thanks Jake, One more clarification... 'tune mysql' means, tuning of /etc/my.cnf or something more than that? Thanks and Regards, S.Senthilvel.

If you're using the default config file that came with CentOs/Fedora then it's tuned for machines with around 256M of RAM. Watch top and see how much of a load mysql is using. Also make sure you have a caching DNS server installed since DNS lookups can drive the load up as well. - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.

RE: [qmailtoaster] Benchmarking POP3
Senthilvel, Is your line chocked? What bandwidth do you have for the connection?. I had a similar issue earlier on one server and upgrading the DSL line from 384Kbps to 1gbps solved it.
