By default davfs2 transfers files to the server asynchronously. Because of this it is not well suited for your task of measuring upload speed. A tool like curl is probably better suited,

If you for some reason must use davfs2 you can

  • set option "delay_upload 0": davfs2 will now upload the file as soon as it is closed. But note: the file is first written to the local cache and only when it is closed it is transfered to the server.
  • set option "debug http": davfs2 will write all HTTP-request lines and all final response lines into your log facility. You can use the time stamps of these log entries to calculate transfer time.

ls stucks forever:
davfs2 is single threaded and so it will not respond as long it is uploading some file. But nothing should stuck forever. If this really happens then something is going wrong.

I need to measure upload speed of our webdav server, So I've mounted a number of davfs2 folders. However I see that if it takes for example 4 seconds to copy 100 files of 1MB to such folder, in reality when I check it on Server side, it may take about 2 minutes. Moreover, when I try to just `ls` on my davfs2 in between (before it actually uploads to server), `ls` stucks forever. Can you probably help with some idea, how to know when actually all files are uploaded?
