Hi Mikey

Can you describe what tool you see the traffic with.... the firewall maybe or is it actual outgoing which at all times is recorded in the message log? Very probable what you see is the RPC talk over localhost/port 31416 over which the 3 parts of BOINC talk with each other. One of them is known as the 'Heartbeat'.

Go discover BOINCview (3rd party), and you will be able to monitor all your machines from 1 display, simultaneous. That will create a little LAN traffic.

(sometimes I use DUmeter, but mostly just watch the little systray icon of the wifi, to identify real out/inbounds.)

Here is one way to prove that the traffic is not BOINC. In the advanced view, activity tab, you can suspend network activity. BOINC workunits will continue to run, but they will stack up and not ask for uploads/downloads. Change it back to network activity before they are done, as the queue could totally empty and the computer just sit there inactive.

I see other network activity this morning. This was another major Microsoft Tuesday "restart your windows day". It is sending some OS downloads to my computers.

I have only installed the clients on three computers, no managerial software. The cooling fan on the laptop pulses in time with the network activity. I thought that was interesting. I am seeing the activity with Zone Alarm firewall. When I exit boinc, it goes back to the Z display from the dancing bar graphs.

D., It does, that's why i asked. My Kerio Sunbelt Personal Firewall does exactly the same, showing the 'in-house' comms of BOINC. The fan pulsing must be the temp up/down due this 60% throttle thing which you proposed to set to 50%, being best achievable with BOINC.

Added: even trained the firewall to not log and not monitor the localhost stuff.... saves cycles.
