Slow read performance on PM863

[webuser1200]

I'm doing rsync between two of the following drives. Each file is several gigs:

Samsung PM863 3.84TB 2.5" SSD MZ7LM3T8HCJM MZ-7LM3T80
​

When running dstat, I see a read of about 140MB and writes closer to 450MB on an HP DL360 G9 2680v3

While running it on HP DL325, Epyc 24 core 7402p I'm seeing reads of 180MB. I was expecting to see faster read speeds. Is that because I'm using rsync?

Yes, rsync usually is CPU limited (single threaded), not IO limited. If you're looking to see actual performance, use something like FIO on Linux.
