The session timer sets the cookie time for those who are LOGGED IN. It also determines how long visitors will appear in who's online.

Have you analyzed the user agent strings of the mass visitors? Five minutes logged in as admin I can tell you precisely what is going on.


EDIT: Looking at your "who's online" as a guest myself, I can see many guests are trying to reply to threads, trying to start threads - these are SPAM BOTS. If I could see their user agent strings i could tell you alot more.

I've never seen a more horrendous web page test from Meehan. Look at this mess - 16 seconds first byte time? And your host thinks this is acceptable? Note: It is not. This server is undergoing a DDoS attack.

Your board is loading 217 requests per pageload when it should be more like 60. You have many 302 errors and even some 404 errors. It's loading over 1MB when it should be around 600kb. You have big problems independent and separate of the attack you're experiencing.
