Subject: Expected performance level of nvme driver v0.8 (Ubuntu 13.10/3.11.0-12-generic)
Date: Wed, 05 Mar 2014 11:35:55 -0800	[thread overview]
Message-ID: <53177C9B.8080606@aeoncomputing.com> (raw)

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
