[Dovecot] General performance of RC5
Hi all,
Switiching to RC5, there is a visible decrease in performance to access via IMAP large accounts (>1G) with mutiple mailboxes per accounts.
In RC4, there was no delay visible by a human when accessing locally. Now it takes up to 4 or 5 secs.
(running on OpenSuse, mysql 5.1.35 for auth, dbox as back end)
Anybody experienced also this ?
Thanks
Joan

When is the delay? When logging in? When opening a mailbox? When
opening a message? Running strace -tt -p <imap process pid> might be
interesting and show what is taking the most time.
I don't think I really changed anything big between rc4/rc5.
It seems to be when reading all the subfolders, hich was very quick in RC4.
I will do your proposal of running strace for further details
