since my board is growing and growing I moved to a bigger server and need some help because the load is getting very high again with 1300-1600 users online. max users online is 1800 with a cookie timeout of 1600.
here are the details:
1) dedicated Server, only one site
2) AMD Opteron 1214 64 Bit Dual Core, 3 GB Ram, 500 GB HD, SuSe 10, Apache 2.2.0, PHP 5.1.3, MySql 4.1.13Max
3) No innobs
4) from the host, dunno
