If you use mpm_worker you can increase your MaxClients without going in outofmemory. "Usually" I calculate my apache parameters this way. Set ThreadsPerChild to 64 (default value). maxClients = (Available Memory / Child memory size) x ThreadsPerChild x K. where K = 0.85. Considering a burst of 200 concurrent requests (your case?), should increase MaxClients to 256 (if you have enough free memory, of course yes). MinSpareThreads = 128 (2 Childs = 128requests / 64 threadsPerChild) MaxSpareThreads = 256 (4 Childs = 256 Requests /64 threadsPerChild) i hope this helps you for future configurations -- Simone Caruso IT Consultant +39 349 65 90 805 --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org
