Greetings,
I am doing some testing and benchmarking with the v0.8 nvme driver in
Ubuntu 13.10/3.11.0-12-generic. With a PCIe Gen3 nvme compliant device I
am seeing sequential (single thread) write and read numbers in the
900MB/sec range. Based on the device I was expecting higher numbers. Is
this an expected level of performance for this version of the driver?
Thanks,
--Jeff

Hi Jeff,
The driver is capable of performing beyond that, but it wouldn't be
possible to say what factors contribute to the performance you're seeing
based on this information.
