Processor Type for Xeon Quad on Kernel 2.6.18
I have installed Debian 4 on a computer with two Xeon Quad. But when I ask some taks, the cpu use reachs only 12-20%. What processor type should I use? I am using 586/686... The SMP and Dual Core options are on.

Not exactly sure what your problem is here. Do you want to see if your core(s) will fully load? If so then install the cpuburn package and use something like burnMMX || echo $? & in a console/console window eight times which will be one for each of your cores then use top and hit the 1 key to show you all eight processors in the output which should be at ~100% load. Now you will want to be monitoring the temperature of your cores when doing this as they will get hot. You will probably never see a fully loaded all eight cores in your machine doing anything other than this as your machine would have to be running a whole lot of processor intensive processes at the same time with the processes being multi-threaded at the same time so they would take advantage of the extra cores as well to have a full load on the machine. To get ~80-90% load on my quad core I had to for instance re-encode a video, compile kdebase and compile the kernel with make -j5 a few times in a row all at the same time, just to give you an idea of what it takes to load them up.
one way i know to load a cpu up, and best bit is it helps others...
download boinc and do some work units for a couple of groups, ie einstein@home, climateprediction.net, seti@home, rosetta...
thats a couple for you, and they all help the world...
when you set the preferences, set cpu usage to 100%, and watch the temp rise, oh and ensure your ready for the slow down...it will, but you may not notice until you try to do a few things at once...
one other thing, with the algorithms being used today, i dont think a quad core would use more than about 50% in general use, except maybe processing something that is cpu intensive, like encoding, or compiling...
12% would be one engine - doesn't sound like it's threaded.
No need to trash the box - just use a small background script to loop forever. Kick off 10 of them - they each run a CPU to 100%, but easily interrupted.
As above use top to split out the CPUs.
But I believe there is something wrong. I have a Pentium-D 3.2 that consumes 24 s to run a mysql´s task. The same task on my xeon quad takes 28s. I believe the xeon quad is operating just one cpu. On the Kernel config smp and multi core are ON.
What processor type should I use on kernel 2.6.18?
How to put mysql to multi-threat?
Yes you are correct, the clock for Pentium D is 3.2 MHz.
But How can I put mysql to multi-threat?
