  • SharePoint \ WebDav bandwidth very slow

    STOP! before you write this is not the SharePoint forum. Close the page and realise your opinion is not what I am after. Thank! I work primarily with SP2010 and a recent client wanted to use only the explorer view which is rendered using its own version of WebDav. I have asked the top industry specialist on SharePoint and they are as stomped as I am as to why is it buffering the bandwidth. So I am asking the IIS gurus about it to see if anyone has come across it. Our test was for 1000 concurrent batch files being imported at the same time, when the file sizes are small(16kb) it copies onto the SHarePoint WebDav at 16KBps. The folder size was 3.2mb. When the folder size is bigger it goes up to 600KBps on the average. when we tested with 3.2GB folder it went up to 5.6MBps. Does anyone know the root cause of this? Is the server doing the throttling or is the client? When we tested with MAC it was even worse because it spent a long time trying to compute how best to negotiate transaction and what protocols to use. Could this be the server?

    Thanks Steve, tried that but had no joy with it. Still doing the same thing.

    Perhaps try the "automatic proxy" solution posted by the Chief Oddball on their blog (it worked for me!): http://oddballupdate.com/2009/12/18/fix-slow-webdav-performance-in-windows-7
