I'm 7+ hours (and 75%) into upload of a 91Meg result file at ~5KBps, with several stalled connections. In the same period, I've uploaded 40+ results to other projects at a more normal ~150K. This issue has been discussed before in this forum. | |

Size will go down by a factor 3 in January with the new applications. | |

Good news GDF, but slightly off-topic. My query is about speed (actually lack thereof), not size ;) | |

jjwhalen, the upload issue you are having probably rests with your ISP or your router/computer's IP/DNS info.

This issue has been discussed before in this forum. I have a similar problem, so it is not just one user. I have run this project for a long time, and I have just noticed this problem in the last week. I don't get a reduced upload speed, but get several breaks in communication, i.e. around 10-20 for a WU, which cause boinc to backoff and my machine to idle, because it can't get new work before the previous is uploaded. This has not been a problem before or with other projects. I can rule out ISP and router problems. | |

It sounds like you're experiencing a routing issue. | |

Sorry, for the delay in response, I've been away.
Over the past five years, across thirteen BOINC projects, I've noted result file upload throughput nearly always above 150KBps, sometimes 2-3 times that. This includes CPDN, which uploads large intermediate result files (~26MB) daily. It also included GPUGRID until a couple of months ago. (<30min to upload a long queue result used to be typical for me.) 5KBps to GPUGRID and 200~300KBps to 4 other projects simultaneously over several hours does not suggest a chokepoint at my end of the route. I recently ran 3 traceroutes to the IP provided. All were ~220ms at the distant end, over 18-19 hops. Not great but not too bad. Times to the end of my ISP's segment of the route were 10~12ms. Traceroute test packets, however, are not the same as file data transfer packets that the server must process instead of throwing away. I reiterate that this is not the first thread in this forum to raise the upload speed issue. shauge reported a similar problem here, and that's 2 datapoints. I suspect there are others who haven't followed this thread and/or haven't bothered to report. File transfer problems do not necessarily affect all users at all times.
