My site got hit with a ddos from 20 different IPs 2 weeks ago and the forum was still running fine with load of 15, though it was slower than normal. Server is a Xeon 3060 with 3GB of memory. Mysql on a separate drive.

I have returned this value to default PHP_LSAPI_CHILDREN=35, it works better now, ddos is not so hard.

Yes, i have firewall but in this case it doesn't help much, connection soft limit is 30, and hard 50. Dynamic Requests/second is 2 and static 20.
On my site during hardest attack was 1400 people online. We got almost the same server.

But with dynamic and static values it looks like load is higher, atm is around 8.
