Hi, After closly looking at some of our mysql performance issues, I've found out that all mysqld threads (I'm using linuxthreads) are running at +14 niceness. This is of course a catastropy. A renice of the main thread does not help. If I do that, I see that all new created threads have again niceness +14. Starting without nohup makes +11 as niceness. I guess there is somewhere a severe bug here. What do you think Tor ?
