An interesting bit of info...

This is how long it takes to broadcast (traverse + send) to bots  
running on 1 ec2 instance, in addition to the server instance

info: 20000
time: 1168.112

info: 20000
time: 1230.546

info: 20000
time: 1095.887

And this is how long it takes to do the same for 20k bots spread over  
3 instances:

info: 20000
time: 5387.765

info: 20000
time: 5380.398

Could there be a Linux networking optimization of sorts for when all  
packets are going to a single server? This is Ubuntu 9.04.

	Thanks, Joel
