I think it would be worthwhile to test using the typical IIS/FastCGI configuration or CLI on Windows. For example, on my server I see a total ~44sec with Apache, and ~31sec using either IIS or CLI (W2K8R2, PHP 5.3.8 x86). If you do end up profiling this I would be very interested to see what you find. Steve
