Docker push is cripplingly slow

Expected behavior

Upload of large layers proceeds as rapidly as small layers

Actual behavior

Upload of large files ( >100MB ) proceeds at less than transfer rates of KB/sec. The result is that an image with a 250 MB layer file took several hours to upload.

There are windows (especially earl in the transfer process) where the transfer is very rapid ( multiple MB/sec). But after a surge, the transfer stalls.

I am having the same problem and since there’s no activity here on the forum, I have created an issue:

I have the same problem. Upload speed has been great for ages and suddenly is now stopping and starting with average speeds less than 1 Mb per minute.
