Thanks Gordon for letting me know that wikimedia servers currently run PHP 4.3.11.
Are there any plans to be running PHP 5.x?
At this time we have no particular plans to upgrade to PHP 5.
To consider it we would need to have a reliable opcode cache extension to achieve equivalent performance to PHP 4.3+Turck MMCache. (Turck MMCache is no longer maintained and is unreliable on PHP 5.)
If eAccelerator (based on Turck) is reliable and safe, we might use that.
I'd like to upgrade to PHP 4.4.0 compiled with gcc 4.0.1. We tried compiling PHP with the Intel C compiler a while ago, and although it was faster, the compilation procedure was complex, and it lacked that free software purity, so we didn't stick with it. But now that gcc has many of the same optimisations (loop unrolling, autovectorization, etc.), the speed improvement over gcc 3.x might be comparable. It would be interesting to do some benchmarks.
