Hi Tom,

We have run over 40K VUs across 25 grinder agents successfully w/o
adjusting reportToConsole interval.

Depending on the size of the responses in the transactions, it is worth
while to get some good network/systems monitoring in place and coordinate
with the appropriate groups.

Thanks,

-Marc
