LOL - you're right!  I didn't mention what my problem might be!

Yes, it was a performance concern.  My site's rather small - basically a 
corporate vanity site - and I haven't been slashdotted yet...so I don't 
think it's a huge issue now...

It just "felt" like it was running slow.  I did just switch from xcache 
to apc - and also adjusted the apc settings to where they might do some 
good.

I also just realized that many of my caching options get invalidated 
when I access the site as a logged-in admin.  That all by itself makes a 
HUGE difference!
