Hi,
I've straced a few dovecot processes after hitting purge on a large
Trash folder (35,000 messages). It looks like it is going through each
message, one by one, and removing (unlinking) each one.
Is there not a more efficient way to do this? If Dovecot knows the whole
folder is being deleted (ie a Trash purge), could it do something clever
with the filesystem to just remove the whole folder?
Incidently, the command that initially deleted those 35k messages to
Trash took about 1 hour to complete on my server and effectively locked
my account out for all that time. There were also an awlful lot of these
output from my strace:
nanosleep({0, 131475000}, NULL) = 0
lstat("/home/virtual/xxx.com/home/admin/Maildir/.Folders.Porter/dovecot-uidlist.lock",
{st_mode=S_IFREG|0600, st_size=0, ...}) = 0
Not sure if there's much one can do about speeding up deleting a lot of
messages though. My webmail client has a 'delete all messages' button
for each folder. If there was an efficient IMAP command for deleting a
whole folder that would be useful in those circumstances.
Interested to know if there is anything that can be improved.
Thanks,
Daniel
