really dumb ssi question

Agreed, DD, on a typical server built for adult traffic AddHandler *shouldn't* bring it down to it's knees - but it may affect page load times noticably if you have TONS of pages.

I have an addhandelr in htaccess to make php work in all html pages on a bunch of domains on the same server.. 100,000+ html pages are affected... Although i cant really compare speed to how it runs without this set (as the pages all rely on php).. Ive had it like this for at least a couple years since I bought the server... and it seems to run pretty fast to me.

I always imagined if every page had php to be parsed anyway it wouldn't affect server load at all. Anyone technical enough to know if this is right?

Also.. say only 10% of html pages required php.. would it then be a bad idea to use addhandler to parse all .html pages for php? Surely the server overhead would be minimal, and never noticable to the eye, I would hope.
