apc vs eaccelerator vs xcache

Question

Im doing research on which one of these to use and I can t really find one that stands out   Eaccelerator is faster than APC  but APC is better maintained  Xcache is faster but the others have easier syntax   Anyone have recommendations on which to use and why

APC is going to be included in PHP 6  and I d guess it has been chosen for good reason     It s fairly easy to install and certainly speeds things up

APC definitely  It s written by the PHP guys  so even though it might not share the highest speeds  you can bet on the fact it s the highest quality   Plus you get some other nifty features I use all the time  http   www php net apc

I always used APC with php 5 1 and 5 2  but I had a lot of  random  errors using APC with php 5 3  Strange blank pages  random out-of-memory errors  They all disappeared when I disabled APC  But that was no option  as it is running a high-volume website    So I tried eaccelerator  So far it has been rock solid and the speed increase is even bigger than with APC  The APC guys really need to spend some time on bugfixing

I think APC is the way to go unless you are using Zend Optimizer on the site  APC is incompatible with Zend Optimizer so in that case you will need to go with something like eAccelerator

It may be important to point out the current stable  unstable and dev versions of each  including date    APC  http   pecl php net package apc  dev        dev          2013-09-12 3 1 14     beta         2013-01-02 3 1 9      stable       2011-05-14   Xcache  http   xcache lighttpd net   dev 3 2     dev        2013-12-13 dev 3 1     dev        2013-11-05 3 1 0       stable     2013-10-10 3 0 4       stable     2013-10-10   eAccelerator  https   github com eaccelerator eaccelerator  dev         dev        2012-08-16 0 9 6-rc1   unstable   2010-01-26 0 9 5 1     stable     2007-05-16

I tested eAccelerator and XCache with Apache  Lighttp and Nginx with a Wordpress site  eAccelerator wins every time  The bad thing is only the missing packages for Debian and Ubuntu  After a PHP update often the server doesn t work anymore if the eAccelerator modules are not recompiled    eAccelerator last RC is from 2009 07 15  0 9 6 rc1  with support for PHP 5 3

In all tests I have seen  eAccelerator performs faster than any other cache out there and uses less memeory to do so  It comes with a nifty script to view cache utilisation and clear the cache etc  eAccelerator is compatible with xdebug and Zend Optimizer   APC is being included in PHP because it is being maintained by the PHP developers  It performs very well  but not as good as eAccelerator  And it has compatability issues with Zend Optimizer   Xcache was made by the developers of lighttpd  benchmarks show it performs similiarly to eAccelerator  and faster than APC   So which is the best   APC   Great if you want an easy cache that will always work with PHP  no fuss  eAccelerator   If you have time to maintain it  keep it up todate and understand how it works  it will perform faster  Long term support not as certain as APC because APC is done by the PHP devs

Even both eacceleator and xcache perform quite well during moderate loads  APC maintains its stability under serious request intensity  If we re talking about a few hundred requests sec here  you ll not feel the difference  But if you re trying to respond more  definetely stick with APC  Especially if your application has overly dynamic characteristics which will likely cause locking issues under such loads  http   www ipsure com blog 2011 eaccelerator-as-zend-extension-high-load-averages-issue  may help

If you want PHP file caching only  you can use eAccelerator directly  Very easy to install and configure  and give great results   But too bad  they removed the eaccelerator put and eaccelerator put from the latest version 0 9 6

In the end I went with eAccelerator - the speed boost  the smaller memory footprint and the fact that is was very easy to install swayed me  It also has a nice web-based front end to clear the cache and provide some stats   The fact that its not maintained anymore is not an issue for me - it works  and that s all I care about  In the future  if it breaks PHP6  or whatever   then I ll re-evaluate my decision and probably go with APC simply because its been adopted by the PHP developers  so should be even easier to install

APC segfaults all day and all night  got no experience with eAccelerator but XCache is very reliable with loads of options and constant development
