[imp] Scalability of IMP

[Kuhl, Oliver]

Hi!

I'working for a local ISP and are looking for a good webmail program to
serve about 100,000 users. I installed imp and I really like it. But I'm not
sure if it handles so many users. In my little testinstallation each click
takes about a second. I'm not sure if it's the imap-operation or the huge
horde-framework, that takes the time.

Does anyone have imp running with thousands of users?
What hardware do I need?
Are there any special hints for increasing the performance with imp?

THX in advance for your help.

Regards,
