Re: Multiple CPU's in Freebsd
Hi Sinisa, Since matt hasn't responded yet, I'll let you know, its not the version of FreeBSD, but the ports collection. The ports collections does not have a version number, people should just fetch latest (using cvsup) however you can fetch by date. A package in the ports collection may require a particulur version of soemthing else (ie OS or Library) but when the package is built it will check and update or error as necessary. I can give you more details if you want Sinisa.

Re: Multiple CPU's in Freebsd
Try this: update your ports, then build the mysql port with WITH_LINUXTHREADS=1. This should result in a FreeBSD native binary linked against linuxthreads instead of libc_r, so it should use multiple processors. Matt Ken Menzel wrote: Hi Rafael, This is not an easy task, there are really only two ways to accomplish this. But first I must ask if you have check how much CPU % is currently in use? Is consistently high? The other cpus's will be used to runs things such as Apache, but mysql will run on one processor. Or, you could start several mysqld processes, each listening to a different port or IP address. To use different IP addresses one would have to enable multiple virtual IP's for that machine. I understand there are some big threads improvements coming for FreeBSD, but I am not sure when they are coming. If you use multiple ports, your application will have to select the port to connect to (such as 3306, 3307, 3308, 3309) or if you use multiple IP addresses then you can use DNS round Robin technique with multiple A records for a single name.

Re: Multiple CPU's in Freebsd
Hi Matt, I am trying it now! Thanks! Seems to work, I am running it on one of the QA servers now and I see it spawning many mysql processes! Very cool! BTW to anyone usings ports after a source install use DB_DIR=/usr/local/var you will get an error at the end of make install, but it's OK! When did this get in!
