This past week I upgraded my PHP form 5.2 to 5.3 and have seen horrible performance.
Has anyone else made this jump and experienced problems? If so how did you fix them?
One such problem originally was apache going from using about 500MB of RAM to gobbling up all 16GB!!! I made some adjustments and now it stays under 2GB but it seems like there are always ten or twenty httpd's running at 75-100% of CPU.
Any thoughts or ideas? The only change on the server was upgrading php, it ran fine before.
