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.
