I am using Mozilla Mail as my mail client at the moment, and I'm on a few busy
mailing lists.  As a result, every month I move a couple of thousand [minimal
size, ~1KB] emails to archive folders.

Moving ~2700 * ~1KB emails from one local mail folder to another local mail
folder took at least one minute [probably two], perfmon showing disk throughput
at 30KB/sec read and 60KB/sec write, mozilla browser and mail during this time
froze for about half that time.  CPU usage was minimal, but explorer also
partially stopped responding [start menu would work, desktop and explorer
windows froze].

My machine spec:

AthlonXP 1800+, 1.5GHz
256MB RAM
10GB UDMA66 IDE disk (system boot disk)
60GB UDMA100 IDE disk (apps/data disk, including mozilla mail app and data)
Windows 2000 SP2 with the latest patches, latest reliable drivers as well

The same task in Eudora takes less than 15 seconds, stops Eudora from responding
during that time, but doesn't affect anything else.

Reproducible: Always

Please update to a newer build. 
Those problems were addresed after the 1.2.1 release.

Using Mozilla 1.3b, I am still experiencing exactly the same problems without
improvement.  Please take another look at this problem.

Confirming again using Mozilla 1.3 release.

I'm using Mozilla Mail 1.3 as my primary email client, all my old mail is in it
as well (the Mail foler in my mozilla profile is currently 112MB).  I intend to
keep using Mail for the forseeable future, because I want a decent mail client
and that involves helping testing it, however to counteract the serious disk I/O
issues that Mozilla Mail has, I have both Mozilla and my mozilla profile in ramdisk!

Mozilla Mail in its current state is a very good email client for 'light' users,
however its performance issues when dealing with large amounts of email will
hamper its development (because power users will generally stay away from it)
significantly.

I'm thinking the severity of this issue should be up'd to major.

should be fixed in latest build.
