    Export download speed seems capped at 1.0Mbps. Is there a setting that is restricting the speed?

    I did a Managed Export yesterday (with 190 references).  The throughput (measured by MB downloaded divided by time to download - NOT by a speedtest) seemed locked at 1.0 Mbps.  the fact that it is at 1.0 as near as I can measure seems to be a setting (or just an amazing consistent coincidence).  

    We do have a corporate VPN which does slow things down.  I do get about 200Mpbs outside of the VPN.

    thanks,

    -jeff

      It's not throttled. It's the overhead of creating the files & folders in the OS, writing the locks to the database, etc.... Also if you have the "Update documents to use local paths for references and links" turned on then it has to open each file and modify it as well.

      I did a test with 1651 documents, 186 folders totaling 461.8 MB. Export with a lock got 5 Mbps. I did NOT have "update ref paths" turned on for this.

      Unlocking all those files, which involved no file transfer, took 3 minutes.

      A copy out of those same documents after I purged all my files, got 5.8 Mbps.

      A single download of all those files via a zip file (zip file was 303 MB) took 29 seconds for 83 Mbps.

      The file transfer method used by ProjectWise is the same for all those methods. It's the additional operations it has to do for each file that bog it down. Even the copy out, which didn't have to update write locks to the database, still has to update the checkout table in the database for each file.

      This test was from our Corporate HQ to one of our datasources on Bentley hosted in Azure.

      Thank you, Kevin, very much.  Recently, I timed 2.3Mbps - THAT I would never believe was a setting anywhere (even Metric).  Your data closes that question in my mind.  Thank you.
