Robert, just wondering about your choice of words in the above. The  
way it's written you are almost stating APC is an alternate to using  
MySQL caching. In my development experience for high traffic sites  
these are two different technologies that can really compliment each  
other. My understanding of APC is it just caches the pre-compiled php  
object code for Apache. Which is better than having repeated requests  
for the same PHP page causing recompile from source every time. The  
actual WordPress page content is not stored as part of the object.  
This is just the PHP object code that still needs to be executed to  
build the output.
