No, I/O stays within reasonable limits. The CPU load is at 60 - 70%, any higher load (even if just a few more sessions) immediately increases it to 100% and sessions are dropped with time-out; increasing the timeout values any higher however isn't allowed by our business (response time limit). > Although you mentioned SSL cache, you didn't mention the value of > SSLSessionCache in your config. Sorry: SSLSessionCache shm:/var/cache/ssl_scache(1024000) SSLSessionCacheTimeout 300 Using dbm was indeed a no-go. > You will find that with high-concurrency hosting, 'dbm' or 'none' won't > cut it - switch to shm instead, and give it some healthy space: > SSLSessionCache shm:/path/to/session/file(2048000) > > Also consider disabling logging to minimize I/O. I'll try increasing the space and disable logging. Is there a best-effort setting for the number of threads versus processes? We're currently setting 25 threads per process (fixed).
