Can anyone *really* explain opcode caching with PHP?

Hi Volodymyr

Thanks for your helpful response. From what you say, opcode caching is
essential and Xcache is the way to go. 

But just to understand - does a php-fpm pool access a single Xcache, or
is there a separate cache set up for each process? I'm trying to get a
handle on the memory implications.

Thanks for the heads up on uWSGI. But my sysadmin skills are basic (I'm
a developer really) and it looks a bit scary. There's not much info out
there, while fastcgi is supported in the php core. For someone who is
not a proper sysadmin, is uWSGI, in its present state of development,
really a sensible way to go?
