Re: thread_concurrency in linux
Andrew Braithwaite wrote: Does anyone know if thread_concurrency works in linux or is it just limited to Solaris and Windows? Hi! That variable only affects Solaris, as the Solaris threading library supports thr_setconcurrency(). innodb_thread_concurrency, however, can affect all platforms, AFAIK: http://www.mysql.org/doc/refman/5.0/en/innodb-parameters.html#option_mysqld_innodb_thread_concurrency I know the general rule is number of CPU's*2 but will this actually have any effect with Linux's threading model? Nope, at least AFAIK. -jay -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: thread_concurrency in linux
I am not sure whether you are talking about innodb_thread_concurrency. If so please check out http://www.mysqlperformanceblog.com/2006/06/05/innodb-thread-concurrency for more details. Innodb_thread_concurrency works on linux.

RE: thread_concurrency in linux
Hi, Just to make it clear; I mean thread_concurrency, not innodb_thread_concurrency.
