Hi Timo, i have reports from few users about lost performance with 2.17 maildir bigger mailboxes ( up to 2 GB ), i also use zlib plugin
what about this patch.....,may not working as i should?

i checked this reverting to 2.1.15 (had only this pre compiled) perfomance gets better with this, looks like the problem is getting more worst with having bigger mailboxes and heavy use of subfolder trees any idea?
I wonder why this would matter. zlib is compressing EACH message individually, so the actual SIZE of the mailbox would not matter (the number of message would matter, though).
Which operations are slow? Folder listing? Actually accessing messages?
accessing , list messsages , copy, move delete operations
it must not be zlib related, that was a guess there are two other patches only maildir related might be a better guess

other patches dont look related to me, however i use a lot of other plugins which might also involved
sorry not easy to measure , but performance here is def better with 2.1.15 , same client setup, no special failures about that in debug logs
Best Regards MfG Robert Schetterer
