I am running Cyrus 1.6.24 for around 400 users under Red Hat 6.2 (2.2.14-12
Kernel) on a Dual Xeon with 512 Mb of memory using the EXT2 file system. As
suggested in the manual, I have set the synchronous bit on the /var/imap and
/var/spool/imap directories. As a result, things go very slow when performing
tasks like adding and deleting folders and changing ACLs on folders. Does anyone
have any suggestions how to get a performance increase in this area? Are there
other filesystems being used without +S set?? Does 2.0.12 improve things in this
area? What about later versions of Linux?
Thanks
Roland Pope
