Is a PHP-only "cache engine" ever worth it?

I wrote a rather small skeleton for my web apps and thought that I would also add a small cache for it.
It is rather simple:
If the current page exists as a file in the cache and the file isn't too old, read it out and exit instead of rebuilding the page
If the current page isn't cached/outdated recalc the page and save it
However, the bad thing about it is:
My performance tests with a page that receives 40 relatively long posts via a MySQL query said that with using the cache, it took even longer to handle a single request (1000 tests each)
How can that happen?
- Should I just remove the complete raw-PHP cache and relieve on the availability of some PHP cache like memcached or so?
