Ridiculous lag on Varlyndria with an 8 gig ram machine.

UPDATE 05/23/12 - Stress test

Tonight I summoned everybody to the guildlobby and even force summoned people there as well. The entire server fought Sharphin in the Guild Lobby's East Wing and while they were fighting I summoned over 220+ NPC humans guards around them. This showed the server could handle A LOT of animations at one time with absolutely no problems. This test was done without bots.


CONCLUSION: This leads me to believe that bots have been causing a lot of the disconnection problems and since we know that now we're going to give it our best shot at eliminating this issue if possible.






This was a very successful test and it shows the server can handle a lot of animations at once. Not one person dysynced tonight. So, what could be causing the bots to do it?

I'm gonna be honest and say I haven't touched the bot code in ages. So if it is bots, I know nothing of that.

It's possible there's an infinite loop in bots, but without technical knowledge and remote access to the machine, it's kind of hard to tell.

A 3-core processor should still allow the system to function... so I really can't say at this point. Not enough information. I'd need to see the CPU of the zone with bots in it. If it's stuck at 33% cpu, then it's probably an infinite loop that was never cleaned up. None of the major servers run bots aside from THF, but they run so much custom code that it's hard to say.

More than likely it is the Bots. When I allowed more Bots per player a few years ago I noticed this issue. Basically the bandwidth will saturate the upload speed. This was back when I had DSL and sucky upstream. It only happened when a player would spawn over 4 bot groups.

We now have 50/5mb and zero issues but I also only allow 5 bots per character to make sure it is never an issue again.
