Where does PHP-XCache save its data?

Question

I've recently installed PHP-XCache and set it up. I can also see files being cached in the admin panel.

But something I do not understand is, where does it save all the data?
Is it stored in a specific location or is it stored in an apache processes memory, if its stored in apaches memory, why does it not need to recompile for every process?

Please help me understand this one!

Answer 1

PHP opcode accelerators save to shared memory. Shared memory can be accessed by all processes.

Answer 2

It is cached in the memory, and it can't be changed to a place on the hard drive, if you were wondering. There's more info at the link below.
