I can't install xhrprof on my online server, they don't support it for now.

I have now the options of using any PHP file caching engine.

What is recommended for file caching, APC or eAccalerator? I was reading 
a lot of + on both sides, but mainly APC should be included natively in 
PHP and is getting developed by the PHP core members. eAccelerator 
though should be faster...

Any suggestions and maybe links for this topic? I found 
http://wiki.typo3.org/Performance_tuning there is always eAccelerator named.

Thanks in advance,

Dominic
