Have these fields any meaning other than statistical, possibly having a restrictive function not to crash LAN's or cause stutter on the web-radio? When entering the new up/download values in the BOINC profile, 4 digits were found to be the limit i.e. 9999 is the highest that can be entered. I thought to have read here, that apart from the little merit value on UD Agent, it does nothing for BOINC, either bragged over in the profile or measured.
----------------------------------------My ISP offered months ago to upgrade to 20mb **, for free,......last night they actually did it, requiring some settings in the 108mb wifi-router to be tweaked and them calibrating the channels all day. This over a copper phone line, almost 30 years old....but thats 'too much info'  This comes from the Unofficial BOINC Wiki:Network Bandwidth From Unofficial BOINC Wiki General The figure of merit for the amount of network traffic that can be accommodated on a specific network using a specific set of protocols. Total effective bandwidth may be less than the maximum specified due to saturation effects when the usage is very high (we call some of this behavior "collisions" because two devices on the network tried to talk as the same time with the predictable result that no other device could understand a thing that was said). The older "Token Ring" network protocol had a lower specified total bandwidth than Ethernet technology, but in a heavy traffic situation the effective bandwidth could be much higher than Ethernet, and delivery times were always more predictable. But it was a slightly higher cost alternative and the "cheaper" and "good enough" Ethernet has become the current de-facto standard network interconnect. ** and still PNG pictures in hi res on the forum are slow  PS This setting may help the other guy here: Network Bandwidth being consumed who was complaining that WCG was eating all of his 6mb bandwidth on a perpetual basis by advising him to switching to BOINC and employing this control ???????

You are forgetting that download speeds are restricted mainly by the capacity of the server. There are some very fast servers out there, attached to very fat pipes - but some servers (like those on a free image host) aren't anything special, and some (like those running a grid project) have fairly heavy demands on them already.
And of course, that 20mb is entirely theoretical anyway. Have you tested it? Even if it does clock near 20mb, you may find that is just the peak value, and it is severely restricted if you try using it at full saturation for long periods of time. And it's 20 megabits, which is 2.5 megabytes per second. And that stuff from the wiki is not really helpful. I'm sorry to say it, but it's true. Irrelevant, at best. |

Absent an answer, put in a ludicrous low number......it does function as a restrictive value
---------------------------------------- , which could help the guys that have to manage and share their total bandwidth in the office!U know it and i know it when Telco's offer bandwidth in MB's...nevertheless. browsing into WCG and visiting some highly picture laden Team threads, and bringing up these PNG appended posts, after cleaning the cache, are displaying virtually instantaneous.......while listening to Pandora Streaming HQ Radio from Seattle......almost feels like sitting on Ethernet rather than Internet......the Telco guy told me i was the furthest away from the switch and were using me to calibrate their system.....works for me. Arrivederla
