FreeBSD 7.x (x86_64) or 2. FreeBSD 6.x (x86) Your machine has 16 GB of RAM. If you ever want to use really large caches in the MySQL server process, you need to use a 64 bit binary, called x86_64 in the MySQL package file names. I have done some googling and made these configuration files for Apache and MySQL? Apache: httpd.conf-start [[... file snipped ...]] MySQL: my.cnfstart [[... file snipped ...]] Is there something you can tune? You cannot tune without knowing which bottleneck you should widen, and how much resources still are available. IMNSHO, you need to start with some configuration, put load onto it (as representative as possible), then watch the system's behavior (take measurements !), and only then determine which part you want to improve. Example: Database caches are good to reduce disk I/O and so to increase performance, but you will not increase caches if your system is already paging heavily (= your RAM is too small). There is no need to change any parameter unless a) its current setting restricts your performance, and you have sufficient resources to raise the limit, or b) its current setting allocates more resources than needed here, which could be used better at some other place. You need some initial run and measurement to check that.

Re: FreeBSD MySQL Performance Tunning suggestions???
Hi, FreeBSD 7 should offer much better performance for MySQL. The FreeBSD kernel developers have found ways to relieve some of the kernel bottlenecks which permit multithreaded applications to operate much better. Regards, Antony.
