The backup is working and the slow backups to AWS seem to be limited to specific files. Uploads hover at about 50kb/s (or lower) and seems to be limited to specific jpeg files. I’m assuming that this means it’s encryption and not compression that is the bottleneck.
Some jpgs (from the same camera, same day (my wedding day)) upload at about ~1Mbs. I’m curious as to what may cause that difference in encryption speed.
More interesting to me is that I have concurrency-max-threads to 10 (Ryzen 5); I would expect that, if this was an encryption bottleneck, my proc would be maxing out. However, what I’m seeing is most cores hovering around 5% or lower, with an occasional core jumping up to 10-20%.
