I had what I believe to be the same problem. I run two different IMail
boxes for two different companies.
Company A is a web/email hosting company. They have about 100 domains and
maybe 500 mail accounts. It's NT 4.0, using the internal IMail database.
It's running IMail 6.06 (which was upgraded from IMail 5) on an older PII
200Mhz with about 200MB RAM. But it runs quite fast and has never had any
problems. On this system, I have several HUGE mail boxes (including one I
filter my IMail list mail into which gets about 1500 or 2000 messages before
I move them each month). I never saw the slightest delay like the one
mentioned in a couple of these threads. Also web mail displays the mailbox
contents almost instantly set at 100 per page.
Now, at Company B, I was able to build a brand new PIII 800Mhz with
super-fast RAID and 512MB RAM. I built it as NT 4.0 with IMail 6.06. When
I built it, it had about 200 accounts using the NT database (It's a BDC in
our NT domain so I wouldn't have to duplicate accounts). There are no users
using it except me although all the accounts are there. From day 1,
performance was marginal. It ran a little slow when checking web mail or
clicking on any folder from an imap client. There was about a 1-3 second
lag before it refreshed. I was perplexed because I could check the
overworked, underpowered server at Company A remotely faster than I could
check the completely idle super-fast machine at Company B which was sitting
on my desk!
Soo...when IMail 7 came out, I upgraded the unused box at Company B to look
at the features and play with it before taking the bigger risk at Company A.
After the upgrade, performance was horrible! I suspected the conversion
issue but even with 1 or 2 message in my box, it took 5-10 seconds just to
refesh the box contents. And in web mail, it took 10-30 seconds. It was
rediculous.
I tried backing up the data and registry then uninstalling/reinstalling
IMail then restoring the data and it didn't change one bit.
I then tried doing the same backup then wiping the machine clean,
reinstalling NT then IMail 7, then restoring the data. Voila! Performance
was incredible! Much better than it ever was running IMail 6 and much
better than the other box at Company A. Almost no noticable delay in
webmail or IMAP.
Now I don't know why reinstalling the OS then Imail fixed it, but it did.
If you have the luxury of a couple hours of down time, it might be worth the
effort to rebuild. Obviously this isn't an ideal solution, but barring a
fix from Ipswitch, it's the only one I know that worked for me.
