My latest performance bottle-neck in PHP has been the frequent memory allocation/deallocation that happens on every request.  I’ve created a speed freak’s patch to help with this by pre-allocating memory and letting it persist across requests.  This removes the interaction with the kernel memory management, and the rest of the internal emalloc/efree calls are dealt with similar to that of a pool allocator.  It’s horribly memory inefficient in the hopes of making some CPU gains.  The patch for PHP-5.2.6 is available, I’d like to hear feedback about it’s success/failure in different environments.

After 4 Years and 179 days WheresGeorge.com has finally come through and notified me of my wondering bills status.  I always thought it would be funny to distribute some dollar bills at a strip club all marked with wheresgeorge.com and a nice description of where I dropped them off at.
