APC vs Zend

[mboehm]

Hey guys,
Recently I did some benchmarks on my personal server using http://pecl.php.net/package/APC and using Zend Optimizer 3.0.1

The results were quite amazing. Using nothing, I ran this test:

/usr/bin/ab -c 2 -n 5000 http://localhost/

I ran the above 5 times and averaged the times to 12.45 seconds for PHP/Apache to serve 5000 requests doing 2 concurrent requests each time.

Then I compiled/installed APC. Ran same test. APC averaged 6.33 seconds. Wow!

Removed APC and installed Zend. Needless to say, Zend was just as slow as without an optimizer installed.

APC's website says don't install both. But I want that sort of speed increase with Kayako.

The Kayako PHP scripts never change so caching them in a compiled state would be marvelous.

Comments/Suggestions?

Thanks,
Matthew
