3) Find the <bwdown> field and increase it to a number like 90000 knreed, I have just tried the trick (I am curious). Will see. I have been surprised to find about 88,000 in my <bwdown> field while I have an ADSL at 512 kb only and throughputs around 30-40,000 ko at best. Maybe bwdown is expressed in uncompressed data? Edit: Oh yes... I forgot it's for Linux only today! If I have read you well I shall have to do the trick again when Windows time comes because the bwdown value will have been reset at the next normal download? Cheers.

Have 245,960 showing as down with a profile limitation of 480 kb, reminding me that the restrictions may still not me functional (was is client or server side)?

Okay, I've downloaded a unit. Here's some data you may find useful.
My initial <bwdown> was very low - I increased it to 90000 as you suggested. AFTER the massive download, the value had increased further to 124730. This is with BOINC 5.10.13, and suggests that that version significantly understates the bandwidth due to many small downloads (some of the tiny downloads clock as less than 100 bytes/s!). The download itself took under 5 minutes, and the transfer rate crept up to about 490 KB/s. On average, it was: 31/08/2007 16:07:51|World Community Grid|[file_xfer] Throughput 321057 bytes/sec This is on a 20 Mbit connection. |

Sekerob: the profile setting is in kilobytes/s, the <bwdown> element is in bytes/s (not that this is documented anywhere....)

The BOINC 5.10.19+ client does a better job of measuring bandwidth. In particular, it does not count the time it takes to connect to the server and initiate the download.
----------------------------------------This matters because many files downloaded are small and the connection time makes the download speed look slower then it really is. Additionally, in the 5.10.19+ that number will be weighted based on the size of the download file. This will give it a more relevant measurement.

One more thing, check what you have set for bandwidth in your preferences. In particular check the fields: 'Maximum download rate'. This field will limit how fast your downloads are the field in the limit that is checked will be limited by this setting.
If you have this field set below 85 then BOINC will limit your downloads to slow enough that you will not be able to qualify. I would recommend raising this to at least 50% higher (i.e. 128). |

Some additional notes:
stderr mentions AutoDock. This is not AutoDock.... stderr also includes the old versioninfo error. Why? Peak memory use (so far) is over 300 MB. The IO read/write byte count is higher than I would expect, even given the checkpoint size. The process has written 3 GB, and it's only a third complete. |

Didactylos - can you give me a workunit where those messages are written?

Oops - thanks for pointing that out. We will remove it the next time we release a version.
