Well now I'm interested more on this..!
No, a hundred users will be max for now.

For the moment I have opcache enabled:
--- php.ini ---
; Determines if Zend OPCache is enabled

; Determines if Zend OPCache is enabled for the CLI version of PHP

; The OPcache shared memory storage size.

..and it runs! Pretty good!
APCu = 88% from cache
opcache = 95% from cache

Yeah, hell!
