Scalability issue with multiple NVMe Devices with one core

[Roy Shterman]

Hi,

scenario is when running traffic over 1 NVMe Device with 1 core I'm 
getting X IOPS and Y% core utilization.

In my perception, when adding more NVMe Devices I should see some 
linearity of the above results, but I'm getting only a small improvement 
in IOPS and still not getting 100% (or closer ) in CPU utilization.

Any suggestions?

Thanks,

Roy
