Hi
We have some oldish servers with ssds - all on 25gbit nics. R815 AMD - 2,4ghz+
Is there significant performance benefits in moving to a new NVMe based, new cpus?
+20% IOPs? + 50% IOPs?

Depends on your current SSDs and the new SSDs. It is highly likely that
most performance increase will come from choosing good new NVMe. In
addition higher clock frequency will increase IO as well but only if it is
a bottleneck.

Hello Jesper,
Assuming your SSDs are server ones with capacitors I'd say the biggest impact will
come from CPUs, up to twice lesser latency, up to twice... or maybe 1.5x more iops in
parallel mode.
If your SSDs are desktop then new server NVMes will be a significant improvement for
writes, too.
