Gah - 1009 threads on linux? You must have a monster box, as each pthread in linux allocates around 2M worth of stack. This equates to around 2G worth of storage alone.
Silly question, but are you paging much during your tests? (I'm guessing you have enough storage to handle this many threads, and other suggestions have been more useful, but this is still a consideration.) > > Settings now for worker mpm : > > > > ThreadLimit 1000 > > StartServers 1 > > Maxclients 2000 > > MinSpareThreads 25 > > MaxSpareThreads 75 > > ThreadsPerChild 1000 > > MaxRequestsPerChild 0 > > > > => Strange thing is that with these settings a ps aux list a little 1009 > > apache processes, so these are no threads but childs ? strange .... > > > > This is linux wierdness.
