Imap timeout with 27k messages...

my folder containing the postfix-users mailinglist currently has 47k messages 
and I access it on a daily basis without problems.

This is on an old Celeron 800 with 2.4 kernel and reiserfs 3. I did some 
benchmarks and found out that only reiserfs and XFS are able to cope with 
that many files. ext2/3 and JFS become very very sluggish with > 10k 
messages.

Is top showing a high system load during reconstruct?

Are you sure your data is on reiserfs? It's kinda difficult to get reiserfs 
with RHEL...

Kind regards,

Gerd
