With good hardware and correct configuration, an all flash cluster
should give:
approx 1-2K write iops per thread (0.5-1 ms latency)
approx 2-5K read iops per thread (0.2-0.5 ms latency)
This is dependent on quality of drives and cpu/frequency but independent
on number of drives or cores.

This is why I’d asked the OP for the CPU in use. Mark and Dan’s recent and
superlative presentation about 1TB/s with Ceph underscored how tunings can make
a very real difference.
