I am concidering making a switch from IIS 7.5 to Apache.
I have already tried running PHP (FastCGI) on nginx but the performance was extremely bad compared to IIS 7.5
Because I am unable to find performance benchmarks (PHP) between IIS and Apache on Windows, I am asking you for your experience/feedback.
I use WinCache on IIS, and I have used eAccelerator on Apache. What about APC?
The switch will be for performance gain only.
Update: I have tried running Apache with mod_php & mod_apc. But the website felt noticeably slower than with IIS. Is this normal? The application is fully APC supported.
