This is not necessarily measured because of WCG, but the slowest project your computer has communicated with. My laptop runs the 'small' SN2S exclusively [small files give high transmission overhead] and is measured by BOINC as having 20KB up and 208KB down, enough to receive the single CEP2, which has that default setting if only 1 task is allowed! Permit 2 or more in your device profile, Read The Friendly Manual, and the BW limit is ignored! Then for all WCG cares you can run a 2400bit modem, and wait a day or 2 to receive 1 new result task assignment. You can force a limit with the newer clients, above 7.0.4x, and some tag lines in the app_config.xml so only 1 CEP2 runs at the time, or however many you specify as allowed for buffering 1-16+no limit. Any more will not process until one of the specified number <max_concurrent> is finished... (problem has nothing to do with nothing to do with Sunday).

Specific topics in the CEP2 forum.
