Hi, think about replacing apache with lighty (www.lighttpd.net) ist faster, more stable and does not need as much memory as apache.
(only ONE) Example: Apache2 website has 200+ req/sec 1200ppl logged in concurrent load 200+ SAME machine with lighty and same conditions (requests and logged in ppl) load UNDER 2. Its the better choice. ;) Simon -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von x-ares-x Gesendet: Freitag, 13.

But I have to start it again i 2 hours. I'm running HLstatsX, so there may be a lot of mySQL queries. Maybe I should test it without the stats. It's really not unplayable, bit there are lags from 1 second, sometimes. when the load rises about 3-4. Don't know, if the configuration will help or more performant hardware, like a new CPU or additional RAM. And about the too many processes: I'm new with Linux, so I don't know every process that can be disabled. But Apache got 10 Child's and Teamspeak too.
