PHP 5.5 to be delayed so Optimizer Plus can be built-in

There is still another week of voting left before it becomes official on March 7th but the results are pretty much complete. PHP 5.5 will definitely integrate Zend Optimizer Plus opcache, built right into the distribution.

This is a good thing for the future of PHP but will require some changes for webhosts.
Since even PHP 5.4 is not widely adopted yet, we are talking 2015 for the masses.

But you don’t have to wait for PHP 5.5, you can replace APC, Xcache and eAccelerator immediately with Zend Optimizer Plus via the newly opensourced code and I’ve made a free control panel for it. Works fine on PHP 5.3 and 5.4 and you’ll typically see a minimum 10% performance boost on busy websites over those other opcode caches because of it’s extra optimization passes.


How to manually install the Zend Optimizer Plus Opcode Cache on PHP 5.4

Feb 13 update! Zend Optimizer+ is now officially open source so these instructions to manually install the binary are no longer needed! Go here instead: https://github.com/zend-dev/ZendOptimizerPlus/

I’ve also written a control panel for it which you can find here:

With Zend supposedly open-sourcing their Optimizer+ opcode cache for PHP, likely replacing APC, I want to preview what I might be dealing with and any limitations/advantages.

However I did not want to install a bunch of unknown zend stuff into php slowing it down or causing conflicts, I only wanted the bare minimum and know exactly what I am installing.

Turns out it’s rather easy once you know what to look for.

WordPress 10% faster with Zend Optimizer Plus vs APC opcode cache

As PHP internals explores replacing the APC opcode cache with an open-sourced Zend Optimizer Plus an interesting benchmark was published. It shows WordPress serving nearly 10% more pages per second than APC while using Optimizer+ (both under PHP 5.5).

APC to be replaced by Zend OptimizerPlus with PHP 5.5 release

There has been a growing discussion about this in PHP internals but now there is a semi-official wiki page explaining what is going to happen with the replacement of APC by Zend open-sourcing their OptimizerPlus opcode cache.

https://wiki.php.net/rfc/optimizerplus

Right now it’s only a “proposal” but if you look at the internals discussion, it’s almost certainly going to happen, it’s just a matter of “when” not “if”.

Given that the few people working on APC would mostly likely stop and focus instead on Optimizer+, APC is now in theory, doomed. Which is a bit crazy considering how much code is out there to take advantage of it’s user cache (which is significantly faster than say memcached on a local single server). OptimizerPlus has no user-cache shared memory support at all, it’s only an opcode cache.

Not sure why the benchmark uses “ancient” WordPress 2.1.1 but in theory this would give even the newest WordPress 3.5 a five to ten percent performance boost.
