From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.18 i686; en-US; rv:0.9.1) Gecko/20010607 BuildID: 2001060713 Searching mail folders with lots of messages is so slow that it's unusable. With Mozilla 0.9, searching a mail folder with 15000 messages (on my local HD) for a keyword in the subject (not even body!) takes 5 minutes and 10 seconds. With Netscape Communicator 4.77, the exact same search in the same folder took 4 seconds. The test was run on a reasonably fast machine, Athlon 1GHz, 256MB RAM, no other apps running. A strange thing is: during its slow search, Mozilla did not use lots of CPU time. While Mozilla was searching, its CPU usage was between 3 and 10%, and the CPU was around 90% idle. Disc access speed isn't the bottleneck either since the mail file resides on a local, very fast HD. Reproducible: Always Steps to Reproduce: 1.Get a large email folder with several thousand messages (e.g. from mailing list). 2.Search -> Search Mail/News messages 3.Search for a keyword in the subject and see how slow it is. Actual Results: It took ages until the search completed Expected Results: Search performance should be at least similar to Netscape 4.77. Twice as slow or three times as slow would be ok for me, but 60 times as slow (the current state) isn't acceptable.

moving to the future milestone.

cc seth because we were talking about this... I find search is really slow IMAP or POP on an account-wide basis compared to 4.x. There is also a bug specifically reported about POP (bug 88449)... don't know if we want to combine into a general search performance bug.

Depends on bug 94602 ... which has just been fixed

I don't think 94602 has anything to do with this. Search is generally slow, IMAP or POP.

Perhaps bug 98141 (currently unconfirmed) might have some relation to this bug?

Please try a newer build. The search should be faster now because a related was fixed recently - bug 94602. laurel, I think he is complaining about local, should be dup of 88449

*** Bug 99881 has been marked as a duplicate of this bug. ***

Still very slow. Searching 2000 messages in my Inbox on Subject (POP3 account) on 600MHz PC running Win98se takes 3 minutes. During those 3 minutes there's very little disk activity and the CPU is about 96% idle! This http://bugzilla.mozilla.org/show_bug.cgi?id=94602 bug was fixed by removing bogus 1/2 second waits - perhaps there are more of these lying around. Running: Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9.4) Gecko/20010913

This should have speeded up by more than 500 times. bienvenu checked in that fix. I am inclined to mark this fixed.

well it took me like 10 seconds to find one message out of only 300 seems too slow for me

what build are you using?

Wow. Has something been commited in the past week to fix this? I just upgraded to 2001011805 and now the searches are done as soon as i click the button I was using a build dated october 12 or so in my posting yesterday

marking fixed, can't find the bug that actually fixed this, but I know because we are scanning 500 headers for each time slice.

I thought bienvenu fixed this?

I think naving was referring to bug 104243

yes, thanks laurel.

OK for me using nov19 commerical trunk build: win98, linux rh6.2 and mac OS X
