I have a huge doubt. I want to install a PHP Accelerator

1. Zend Optimizer 2.5.7
2. turck-mmcache-2.4.6
3. eaccelerator-0.9.2a

Which is better to go for. I read that http://www.clarkconnect.org/forums/showflat.php?Board=webserver&Number=6...

The website says eaccelerator is better. But I'm actually afraid if I i encounter some bugs when I go live with it.

We use Turck MMCache on Wikimedia, and it's served very well. MMCache is no longer being maintained since the author was hired by Zend a while ago, and iirc it doesn't support PHP 5.

eAccelerator is a derivitive of MMCache, continuing to maintain and extend it since the original project was dropped. I'm using it experimentally on my own site, on PHP 5; I haven't noticed any problems but haven't extensively tested it.

These are both free/open source modules, like the PHP core itself.

I think Zend Optimizer is more trustable. Please suggest me a good solution

Zend _Accelerator_ probably does a fine job, but it's not open source (further I get the impression it's only available now as part of an expensive 'Zend Platform' product). This may not make a difference to you, but it is a factor in decisions for Wikimedia, and we haven't used it.

Zend Optimizer is a separate product, and seems to be not quite the same thing.
