Log download is very slow #506

Open GekoCH opened 6 years ago

GekoCH commented 6 years ago

I just updated to the newest GitHub Mavproxy version but still I have a strange behavior during log downloads via Mavproxy. (I use a linux machine) The first 97% of the logile is downloaded very fast via log download "nr" However the last part takes ages and displaying the log download status reveals a lot of retires. After the download here the message: Finished downloading log32.bin (11093798 bytes 503 seconds, 22.0 kbyte/sec 2856 retries)

And during download I get a lot of artifact data (see image). Is this a bug or how can I improve the log download?

What do you consider "very slow"?

You should expect 250kB/s over USB on master.
