So basically xcache doesn't write anything on hard drive? Everything is in memory?I dont understand your question, xcache compile any php state in memory (SHM) and get the compiled version from memory.
I use xCache from version 1 in vbulletin for years and in xenforo with great results. The past week i change xcache to APC because xCache dont suppor php-Cli calls.
Yes all opcode cachers save to shared memory.So basically xcache doesn't write anything on hard drive? Everything is in memory?
What u mean by it doesn't handle php-cli calls? Means u run any php script from shell and xcache doesn't handle it?
