Have been happily running a FreeBSD-based MySQL server for about three years
now, first with 4.x and more recently with 5.x. This is the back end for a
fairly busy web site, currently about 5M pages per month, 1.5M+ queries per
day. FreeBSD and MySQL have been rock-solid. The only issues started
coming in when the traffic overwhelmed the previous CPU and MySQL would need
to be restarted once in a while.
Currently running dual Opteron 242s with 2 GB, and there has not been a
single FreeBSD or MySQL glitch in the 45 or so days that the system has been
in production.

Subject: High volume AMD64 MySQL server -- FreeBSD vs Linux?
Hello AMD64 development team,
I am a long time FreeBSD user and my current project requires me to build a
stable, high volume MySQL database server.
I know someone who is currently running a very high volume Linux based dual
opteron MySQL server.
I have heard and read bad things about running MySQL on intel based FreeBSD
systems -- espeically those before the 5.x branch. I guess it had something
to do with how threading is performed on FreeBSD vs on Linux.
Does this threading issue still apply with FreeBSD/AMD64?
Do you think the FreeBSD/AMD64 project is ready to be used as the OS for a
high volume production MySQL server?
If the FreeBSD AMD64 team thinks it is worth it, I would like to offer to
conduct some assisted benchmark tests on the system I have built (see below)
and we can compare them to benchmarks on a AMD64 linux distribution from
someone willing to cooperate on their side (perhaps Mandrake).
We could let both sides assist in various performance tweaks (kernel
tunings, mysql config settings etc) and you can publish the results if you
would like.
I would much rather run this Opteron server under FreeBSD if it were as
stable and performed as well as the Linux version.
The system I have built consists of:
Tyan S2880UGNR Dual Opteron Motherboard
2 Opteron 240 CPU's
2 gigs (2 1gig modules) of PC2700 Registered ECC DDR memory LSI Zero Channel
Raid Controller (Megaraid 320-0)
4 Fujitsu MAM3184MP U160 Scsi Drives - 15,000rpm 18gb
- these will be ran as two 2 drive raid 0 channels,
one for MyISAM tables and the other for InnoDB.
1 80 gig ATA133 or SATA drive for system and logging.
Let me know if this is something anyone there would be interested in doing.
