Hi all,
cpuset is the command to set a cpu affinity,
there are details @ http://bramp.net/blog/post
vmstat -z is the command you need to determine whether there is contention
for mbufs.
although the cpu usage does not suggest the system is memory constrained.

On Mon, Aug
vmstat switched on "vmstat 3" and send us the output.
I expect we are going to see alot of interrupts.

I would recommend that you start with PMCStat and figure where the
bottleneck is,
Given that you have a two threads and your CPU is at 100%,
my a apriori guess would be a contention for a spinlock,
so I might also try to use LOCK_PROFILING to handle on this.

Apologies, I neglected to clarify, I am of course talking about Kernel
Threads.

Any idea's how to encourage the scheduler to adopt this behaviour ?

No, not at all.
I am using 6.2 and 7.0 at the moment, I will build another disk with FreeBSD

I know I am going to really show my FreeBSD ignorance here, but this is a
patch of FreeBSD 8.0 Current isn't it ?

if you like. All you need is to have PHP loaded on the machine and then
create a single MySQL database. Let me know if you are game.

ut at the end of the day, I want to know what my database server is
able to achieve in the real world when it comes to stuff like inserts, updates,
searches.
I'll send another e-mail in a minute. Gotta finish lunch :)

o a single SATA drive, the server was quite a
bit faster when setup with the raid card and 4 10K Raptor drives. I have the
benchmarks here if anyone is interested. I also just ordered 4 more 10K drives
and I'm going to re-run everything in order to
t's a real nice setup and never had
any problems.

my benchmarking with apache shows that it does seem to run faster on 32 bit Xeon
than 64 bit Opterons. PHP ran a bit faster on the Opterons, but nothing major.

Thanks Sunil,
I'm running a completely stripped down apache and PHP config here. As you say,
it makes a huge difference if you don't rely on those modules.
Thanks!
