Performance evaluation of a web server with PHP and PostgreSQL

Quite interesting material " Serverwide Performance Benchmarking " which presents a study of changes in web server performance depending on the type of file system (Ext3, ReiserFS, JFS, XFS), PostgreSQL buffer size (shared buffer) and the availability of opcode caching in PHP (Advanced PHP Cache ).

XFS is the absolute leader among filesystems, and ext3 is the usual ext3 mode writeback noatime.
The little efficiency of PHP APC looks a little strange, but the author explains this with the simple and easy site, “there is not much you can cache, but on large projects it will definitely help.”
