Allen Lee updated COMMONS-31:
-----------------------------
Summary: performance (was: networking performance)
More data from 3/11 pretest, 15 participants:
CPU utilization averages around 3-5%
iftop reports data transfer averages drops about 40Kb to 105Kb per second from server->client and 30-37Kb from client->server

> Based on iftop, the network traffic to/from each host averages around 145 Kb for server -> client and 40-50 Kb from client->server (see below snapshot for a badly formatted example).
> We should be able to improve performance by carefully monitoring what data we send, and how frequently we send it. That would be in processRound2d() and the SERVER_SLEEP_INTERVAL in ForagingServer.
