Hi!
Yesterday rsync finished after 3 hours. I had a lot of new large files (virtual machines) and I have added numerous small files (so taking longer than usual should be expected), and the reported speed was 1.94M bytes/sec: --8<---------------cut here---------------start------------->8--- 2021/09/12 15:53:10 [8103] Number of files: 347,684 (reg: 306,343, dir: 24,017, link: 17,324) 2021/09/12 15:53:10 [8103] Number of created files: 82,443 (reg: 58,416, dir: 9,455, link: 14,572) 2021/09/12 15:53:10 [8103] Number of regular files transferred: 58,441 2021/09/12 15:53:10 [8103] Total file size: 466.40G bytes 2021/09/12 15:53:10 [8103] Total transferred file size: 237.44G bytes 2021/09/12 15:53:10 [8103] Literal data: 21.31G bytes 2021/09/12 15:53:10 [8103] Matched data: 216.13G bytes 2021/09/12 15:53:10 [8103] File list size: 4.39M 2021/09/12 15:53:10 [8103] File list generation time: 0.002 seconds 2021/09/12 15:53:10 [8103] File list transfer time: 0.000 seconds 2021/09/12 15:53:10 [8103] Total bytes sent: 21.33G 2021/09/12 15:53:10 [8103] Total bytes received: 16.11M 2021/09/12 15:53:10 [8103] sent 21.33G bytes received 16.11M bytes 1.94M bytes/sec 2021/09/12 15:53:10 [8103] total size is 466.40G speedup is 21.84 --8<---------------cut here---------------end--------------->8--- Unfortunately I deleted incidentally almost all earlier logs, but I'm pretty sure the speed was usually much higher. In the logs left I see, to my surprise, that sometimes the speed was even lower, e.g. 2021/06/02 12:58:26 [14079] sent 3.39M bytes received 137.16K bytes 190.76K bytes/sec but sometimes it was also quite high, e.g. 2021/06/03 15:31:14 [16281] sent 57.63G bytes received 149.27K bytes 50.98M bytes/sec The computer, the router and the QNAP NAS are in the same room. Some time ago I tested the speed of computer-NAS connection. Unfortunately I forgot what programs I used, I don't remember also the exact value but it was satisfactory (100M bytes/sec?).
