Have a question about requirements: its says that "we recommend that vBulletin 3.8.x is run on PHP 5.2.8 with APC (or a similar opcode cache) and MySQL 5.1.30 for best performance and stability."
Does that mean The version has to be exactly the one listed above for optimal performace or can it be a newer version as long as its not older then the version listed above.
You can use vBulletin 3.8 with PHP 4+, but if you have 5.2.8+ or 5.1.30+, you will get increased performance speeds.
Ok, but the thing that concerns me more is that i do have the newest version of each installed on my server but which is better, to have the latest version or revert to the version that VB recommended for best performance?
