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.

1. FreeBSD 7.0-RELEASE amd64
2. Apache 2.2.8
3. PHP 4.4.8 (or may be PHP5, what do you suggest?)
Server's hardware configuration is as follow:
2 x Quad Core Xeon E5450 3.0GHz,2x6MB,1333FSB
16GB (8x2GB Dual Rank DIMMs) 667MHz FBD
6 x 450GB SAS 15k 3.5 HD Hot Plug
PERC 6/i, Integrated Controller Card x6 backplane
PE2950 III C5 MSS R10 Add-in PERC 5/i / 6/i 1 S
TCP/IP Offload Engine 2P
Broadcom TCP/IP Offload Engine functionality (TOE) Not Enabled
For FreeBSD 7.0-RELEASE amd64 Which MySQL 5.0 would be used ?
1. FreeBSD 7.x (x86_64)
or
2. FreeBSD 6.x (x86)
I have done some googling and made these configuration files for

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.

DOn't forget, Edit your /boot/loader.conf to allow your MySQL to grow up to about 8GB (for starters). People forget this about as often as they forget to put INDEXES on their tables. Speaking of that! Turn on your slow_query_log... set it to 5 seconds and monitor the slow_query_log file. Are you going to replicate? If not, disable log-bin (you have skip-networking, so I assume you are not setting up a master/slave). Only reason to do log-bin is to fill your disk up with files you will never yse. Up query_cache_limit=8M (depends, may not matter for your site). (That is the max limit per query to cache...). Keep an eye on your cache fill rate and up those values if you need to. Keep an eye on your table_cache... table_cache=1024 may be fine, but if you have 4000 tables, that may need to be higher. Set your key_buffer higher (depending on your site) --- several 100GB. Connections can *probably* be lower... the only reason to have a real hig number for connections is to get your machine to swap. :p Oh, check out the my-huge.cnf file that comes with MySQL... I think it is in /usr/local/share/mysql/ or somewhere good tips there. Good luck.
