What php accelerator do you use?

Is anyone using php accelerator of any kind? Which one whould you recommend?

In the past I used several accelerators, from zend (not free) to ioncube, to eaccelerator

Which one is currently the most reliable?

APC cache is not really a php accelerator, right?

As far as I know, no APC isn’t an accelerator in the strictest sense of what a php accelerator is. It’s a caching mechanism, I think, but if you’re looking for a performance boost APC is still a good bet. Personally, I don’t get too hung up on the difference and use APC on a couple of my own servers.

I also use eaccelerator too though mostly because it’s bundled with WHM and the performance doesn’t suck. I can say that I’ve heard the performance of Zend is negligible, though I can’t find the article right now (it was a while ago too so Zend might have gotten better).

I use memcache for caching of lots or objects, but now also looking for a way to boost performance of php scripts.

I’ve used eaccelerator in the past, but then stopped using it when I moved to another server and just never got time to install it again. I’ll just have to try to see if it works, there has been a lot of new versions released and also last time I’ve been using it, it was with php < 5.2
