I believe I have a simple but highly effective fix.

Since the vast majority of forum traffic is for non-logged in user AND, since the only time a forum page changes is if a POST is made … why not implement a very basic disk caching system that does the following pseudo code:

// Front page

---

if (not logged in)

…….. serve disk cache

…………….if (disk cache not present)

……………………generate page and save to disk

else

……..generate page (PHP)

// Topic page

---

if (not logged in)

……..serve disk cache

……..if (disk cache not present)

…………….generate page and save to disk

else

……..generate page (PHP)

// post a comment function

---

delete Topic cache for non-logged in users

delete Front page cache for non-logged in users

The benefit being, now for any non-logged in user – the Front page and individual Topic pages will be cached once some submits a new comment.

And if you are logged in, non of this effects you.
