Many variables not yet specified:

The volume, type, and size of messages and attachments, (spam and
genuine) is more important than user-count.

The number of SA (and other, CLAMAV, for example) tests, and where htye
are being applied.

The bandwidth of your connection.

The OS, and what *else* it is running on the box?

Which webmail toolset, and what languages?

And if you have used Exim / some other MTA previously with comparable
performance or not.

You might want to start by isolating what processes are using what
percentage of resources.....

SA, and/or the httpd and webmail are more likely than Exim to be the
resource hogs.

More info needed.... *Much* more...
