I have a Drupal website that I've done quite a lot of optimization to in order to reduce memory usage, but it's still running at ~50MB peak per non-cached page load.
Given that I've run it on a local dev machine (Mac OS X 10.6 running MAMP w/ Apache2 and PHP 5.2.17 with XCache and Zend Optimizer) and on another webhost (A CentOS 5.8 machine running Apache2, PHP 5.2.17 with Zend Optimizer) -- which used 14mb and around 30mb respectively -- I'm getting the sneaky suspicion the issue lies with my present webhost (Running Nginx on Debian 6 with PHP 5.2.17 with Zend Optimizer and XCache).
Is there any way of easily benchmarking PHP memory usage across varying server configuration?
Thanks!
