Hi,
I recompiled Dovecot with Lucene FTS to try to improve iOS 7 IMAP search speed.
Unfortunately this does not seem to help.
I have 60 mailboxes, totaling 300 MB; lucene-indexes is 30 MB in size.
% doveadm mailbox status -t all '*' messages=16335 recent=0 unseen=1736 vsize=280049586
Searching for a single word which is present in two messages of one mailbox takes 40 seconds to return. This is true whether or not fts is enabled.
you mean, from the IOS device?
doveadm search takes much less than 1 second to do the same search.
% time doveadm search BODY cython d8f09230c97af952b60c0000c1443b93 1 d8f09230c97af952b60c0000c1443b93 2 doveadm search BODY cython 0.18s user 0.05s system 99% cpu 0.230 total
With fts disabled, it takes about 6.5 seconds. This is still a long way from 40 seconds.
Is there any way I can make dovecot perform better here?
if its fast on the server, can you tell, whether the IOS device actually uses the server for searching?
