performance issue of Intel P3700 SSD (PCIe 3.0 Interface)

Solution Verified - Updated -

Issue

We are currently experiencing bad performance using Intel P3700 SSD in several systems under RHEL6 and 7.0 . We see write/read throughput of only 6MB/s, but would expect 100s of MB/s. The Intel P3700 SSD has a PCIe 3.0 Interface, the nvme driver is driving it.

Environment
