YMMV ...

As with all complex server side applications it can be a real 
CPU/Memory hog. Be sure to examine the following if you expect some 
noticeable workload :

- Read the PERFORMANCE tips in the doc section
- Use a fast IMAP server / Database
- Use a PHP accelerator
- Be sure to get a clean configuration and maybe disable features which 
are marked as "generate load on the server" like attachment icons, 
previews etc.
- Get some big amount of memory if your users handle big attachments
- Use PHP with the recommended features compiled in (mcrypt!!)

With a carefully tuned installation some guys operate large userbases 
webmail systems with HORD/IMP.
