Description
I'm not 100% sure that this is a bug, but it seems weird, so wanted to capture the data.
The last hour of the upload looks like this:
KiB (RX Bytes/minute) 325.39 |.|....................|.................................... 271.16 ||||......||||.........|.|..............|................... 216.93 |||||.....||||...||..|.|.|..||||||.....||||............||... 162.70 ||||||.|||||||||||||||||.||||||||||..||||||.|||.......|||||| 108.46 |||||||||||||||||||||||||||||||||||||||||||||||||||||.|||||| 54.23 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 1 5 10 15 20 25 30 35 40 45 50 55 60 MiB (TX Bytes/minute) 77.68 ||.|......|||...........................||.............||..| 64.73 ||||......||||..................||......||.............||||| 51.79 ||||......|||||...|..........|.|||.....||||...........|||||| 38.84 ||||......|||||.||||||.|....||||||.....||||...........|||||| 25.89 |||||.....|||||||||||||||..||||||||....||||...........|||||| 12.95 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 1 5 10 15 20 25 30 35 40 45 50 55 60
Although there are minute average peaks in the 70-80 MB/s range, there are also valleys of several minutes in the 10-20 MB/s range.
The hour averages look like this:
MiB (RX Bytes/hour) 88.66 ....||...................................................... 73.89 ....||............................||........................ 59.11 ....||............................||........................ 44.33 ....||...........................|||........................ 29.55 ....||...........................|||........................ 14.78 ::::|||::::::::::::::::::::::::::|||:::::::::::::::::::::::: 1 5 10 15 20 25 30 35 40 45 50 55 60 MiB (TX Bytes/hour) 39.25 .|...............|.......................................... 32.71 ||...............|.......................................... 26.17 ||...............||......................................... 19.62 |||..............||......................................... 13.08 |||.............|||......................................... 6.54 ||||:::::::::::||||||||||||||||::::::::::::::::::::::|:::::: 1 5 10 15 20 25 30 35 40 45 50 55 60

Note that the blobxfer downloads are 80-90 MB/s while the arv-put uploads are 20-30 MB/s in the hourly averages.
It's totally possible that there are environmental factors contributing to this
