Good question. try mysqladmin -p status yast by putting load to it. and by using the top. then i get al the load on the master pid Sorry, but, afaic, You don't understand what threads are. Thread is subprogram, which is executed simultaneously with main program (main thread) in _same_ process. PID is process parameter and additional threads don't create additional PID's. Multithreading, in fact, allow You to not create additional processes (which is resource-consuming task), but do parallel computations inside _one_ process. So master pid _must_ take all load, if it act as multithreaded program.

Re: problem with mysql threads on freebsd
Leo, I believe there was a conversation about this subject several weeks ago, in which the conclusion was that a good reason to use Linux, in preference to FreeBSD, for database servers is that Linux multi-processor support works and FreeBSD doesn't. --Erv sql,query At 09:42 AM 6/11/2002 +0200, Leo De Geer wrote: but in my case its not good to have it that way im having one dedikated dual server for the sql and now im yust using one cpu for the sql questions. i nead it to start sub conections to the sql to serv all my conections good. -- MVH C.

RE: problem with mysql threads on freebsd
We are ruing a box with freeBSD and MySQL with twin processors It looked like it was using only on processor but we decided that it was the way FreeBSD's threads work? There seems to be two problems with ruing MySQL on FreeBSD. One: Seems not to use both processors (on twin system) Two: All ways a load on 1 even when the system in not at hi load (seem to go down when it is!) What is up with freeBSD or MySQL.

Hello Leo De Geer [EMAIL PROTECTED], the problen nr 2 i dont have but the server we have dont handle the load on one cpu. at the moment we are runing the sql on a linux instead (same hardwere) but i sucks. alla auter servers is freebsd and they run mutch beter Why MySQL on Linux sucks?

Do not assume that the way Linux manages threads is the only one. Mysql on FreeBSD does create threads; they are just not visible via top (in fact Linux is the only OS that shows threads in top). FreeBSD's threads system, however will not put those threads on multiple CPUs. You can work around this by building the mysql port with LinuxThreads: cd /usr/ports/databases/mysql323-server make WITH_LINUXTHREADS=yes This is only useful if your system is dedicated to mysql, though. If it is a combination webserver/database, the other CPU will be busy enough serving webpages, and FreeBSD's regular threads will do fine. thanks that is the thing i have looking for. regards leo -- MVH C.
