Hi,
I'm working with dovecot 1.0.beta2 for pop3 only and have set index=memory, so no indizes are created on the disk. pop3_uidl_format is set to %f. The maildirs are located on an nfs-share. So generally, this setup is very similar to what qmail-popup and qmail-pop3d does. However, everytime I'm switching from qmail-pop3d to dovecot, the system load increases from less than 2 to more than 30 (and later up to 60 and more). The problem is I/O, probably caused by nfs-access. But what is causing this accesses? qmail-pop3d just takes filenames as UIDL, and moves the mails from new to cur, reads them to send them to the client or deletes them. This is working fine. But what is dovecot doing? There must be a lot more things that cause that high I/O load. Indizes are disabled, so they cannot be the cause any longer. Any ideas? I just want to switch to dovecot at some point finally without having qmail-pop3d as backup.
Regards Marten
