APC or Memcached?

steitieh · Jul 10, 2015

Hello guys,

just wondering which is better to use for wordpress blogs or forums.

I know there is APC and memcached installed with Centmin, which I'm waiting to add to the config file. Which I'd like to ask which one is probably better suited to a VPS or a dedicated server?

And what is the difference between APC and Memcached?

APC caches chunks of PHP code in to RAM so that when you need to run said PHP code later it is already in the RAM and you will utilize less Disk I/O. Memcached stores static information in the RAM and makes it easily accessible, primarily used to store MYSQL information for quick and easy access. I would actually recommend a combination of APC/eAccelerator/xCache and MemCached for optimal performance, however, I wouldn't recommend utilizing EITHER unless you have a significant amount of Memory/RAM assigned to your server.

Somewhat what I was getting at. What I mean is I recommend at least having 1GB of RAM dedicated to EACH of the two services, depending on the size of your website, maybe more.

Both APC and Memcached reduces the load of a particular Machine. It completely depends on the purpose of usage of VPS or Dedicated server.

you can use anyone of these. It will not harm the performance of VPS or Dedicated server.

Not necessarily true.

APC and MemCached are both great tools to use to improve the performance of a site.

However, like everything, if it is not configured properly, or you try to run it on hardware that cannot support it (not enough memory), you can in fact make things worse!
