Stalling Uploads hang 15 seconds between 100mb chunks

Steps to replicate it:

  1. Upload Large File

I have my chunks set to 100MB for uploads. Each chunk uploads very quickly (30-60MB/s) and then takes about 15 seconds for the next chunk to start to upload. I have searched and searched but can’t seem to find a proper answer for why this may be. Both client and server have plenty of processing power, and neither is giving any sort of error in the logs. The put requests are simply about 15seconds apart in the server log. Any ideas are appreciated


It’s hard to tell without more details, are you talking about the webinterface or the desktop client? Which versions? How is your setup, there are a few tricks and quirks for the large file uploads (check documentation). Perhaps your problem is a bit similar to this one:

Reverse proxies can also block and slow down things, do you use one?
