My upload speed for a single large file (over 83GB) is very slow. Multiple smaller files typically saturate my internet connection over ethernet, but I've been having trouble with this one large file.
I use my own google creds. Whenever the transfers are successful and fast the API activity looks good. Whenever it switches to the large file it slows down considerably (as you can see it's been running since 4/16 and not much movement (besides the spikes).
So I followed your recco and rm'd the flags. I also added the drive-chunk-size flag and it seems to have helped a little bit. It's bizarre that other, smaller, normal files saturate the connection at around ~2.5 MB/s, but this file is always less than 1.0 MB/s.
It's actually gone down from when I took the screenshot, btw. It's at ~750 kB/s now. I also notice that rclone is using 100% on the CPU core that it's running, and it consistently does so. It's also using a crazy amount of RAM!
Could it be that the number of checkers are taking up the rest of the bandwidth? I do have a massive number of files in the source folder that I run the copy on:
Copying that folder specifically fixed the issue! This time it only had to transfer/check ~800 files instead of ~1.7 million files. Saturated the connection completely.
