Hi, I'm not sure if this is really the right list for this, but I got no response from the "users" list, so I'm wondering if some of the developers might be able to shed some light. Sorry if it's inappropriate to mail this list with these questions.
I've been reading a bit about Apache2 performance tuning. I'm particularly interested in reducing the memory usage as much as possible. I'm running apache2 on redhat 7.3 servers with very heavy http traffic. I'm wondering if it might be wise for me to try to use the worker MPM rather than the default prefork. Does anyone have any real-world experience with this? Our users are allowed to run any cgi scripts they want -- could this cause a potential problem with worker? Also, I recently encountered a problem with the mutex device - I'm using the default AcceptMutex setting, which is sysvsem, but it is leaving semaphores around when httpd is restarted. It seems like the two main recommendations for fixing this are to either increase the max number of semaphores in the kernel or use AcceptMutex fcntl instead. Again, has anyone had any experience with this? It's probably also important to note that the files that apache serves are nfs - does this give me a disadvantage if I try to use fcntl? And if I increase the max semaphores in the kernel - isn't it just a matter of time before they all get used up too? Thanks! Kristina -- Kristina Clair Datarealm Internet Services www.serve.com
