Can anyone explain me... why on guest ubuntu, cpu is faster than on host ubuntu... with 'pyrit benchmark'

System: CPU: i7 3770 (HyperThreading Enabled)
RAM: 24Gb
GPU: Nvidia GTX 650 Ti Boost

I have a dualboot:

Windows 7 & ubuntu 12.04 lts

on Windows 7 installed vmware workstation 10, and guest os ubuntu 12.04 (the same as secondary boot).

Running "pyrit benchmark" command on both systems. Using only CPU (GPU driver is not installed)

On VMware Guest Ubuntu, i get about 617 PMKs/s * 8 cores ~ 4700-4900 PMKs/s

and on Host (secondary boot) Ubuntu i get about 213-250 PMKs/s per core ~ 1700 PMKs/s



Why?

And how can i get these rates in host Ubuntu? Thank you.

I don't know but your peformance is dismal on both..

My cheap Athlon 640 X4 should get about 1/2 the performance of your I7 3770...but its averaging about 99% of your results.

Try A live linux distro with pyrit , just to see if there is something wrong with your ubuntu install?

#1: 'CUDA-Device #1 'GeForce GT 240'': 5169.6 PMKs/s (RTT 2.6) #2: 'CPU-Core (SSE2)': 595.4 PMKs/s (RTT 2.8) #3: 'CPU-Core (SSE2)': 618.9 PMKs/s (RTT 3.0) #4: 'CPU-Core (SSE2)': 625.9 PMKs/s (RTT 2.9) #5: 'Network-Clients': 0.0 PMKs/s (RTT 0.0)
