VPS - Which PHP Cache Should I install and how

[akreider2]

I need to install a php cache. Maybe APC (Alternative PHP Cache)?

Which one is best?
Any suggestions about how to install it?

My php software is only about 2mb - so I'm hoping that I could
1) have it all stored as op codes in the memory

and perhaps
2) have it all stored in memory period (eg. no file loads). Though maybe this is a waste of RAM?

Hi Aaron,

APC is a good option. You can find the installation tutorial here.

http://php.net/apc.setup

You can also consider eaccelerator as an another alternative. Take a look at the list of php accelerators here.

Please open a ticket with support, if you need any assistance on php accelerator installation.

I'm running suPHP. Apparently that doesn't work with APC.

Should I use another cache system, or is there a way I can get APC to work with suPHP?

Could I do something like have all the of scripts for my software run under the same user so that they could share the cache? (Eg. if my domain is running 5 php sofware packages, create a special user for each of them - so this would make it less secure, but allow for caching.) If this is possible, how would I do it? Could I define all the scripts in a directory to run under a specific user?

I'm interested in doing this because loading my 1-2mb php software takes 500ms (all the require_once() statements for my 10-20 libraries).

My entire software package is about 3mb. So I'd love to have it all converted into opcodes and stored in memory.

So the load time is more around 400ms.

120 ms is connecting to the database (my ping time between the database server and the webserver is 35-40 ms as they are in different locations)

Otherwise, the slow time problem seems to come from having functions that aren't in classes and defining global arrays (I have a lot of global variables).

I'd bet there's a PHP to C converter out there somewhere.
