FP Server Extensions do not perform well with large site or large files. For large sites try to create independent FrontPage "child webs" or "sub webs".
It's very important to trim files created by FrontPage when they grow larger then a few megabytes, sometimes even a few 100s KBytes. For example, a guestbook over 8MB can easily max out the CPU for minutes, at each new guestbook entry.
Example of FrontPage "webbot" that create files:
- Guestbook
- Form "Save to" File
This is especially important nowadays since they are thousands of automated scripts looking for these guestbooks and forms to send SPAM information.
