Hi Xiaolong,

I tried this benchmark on my native haswell box, but it works. and get
unstable/better performance value.
This patch may be has some problem when it run in guest OS.
Did you run the case on a guest OS or a native OS?

Any other benchmark did you test on any other machine? If so, what's the
result you get?

Regards
Alex

Hi, Alex

The unixbench is launched on a native OS.

So far, we have just found issues with unixbench on two Ivy Bridge
machine.

Thanks,

Hi Xiaolong,

Thanks for the info. Do you have any other benchmark data for this branch?

Hi, Alex

0day system should have launched several benchmarks for branch with your
commit, which specific benchmark are you interested in? I can search it
in the system.

Thanks,
Xiaolong.

That should be memory related, multi-thread map/unmap benchmarks. guess
maybe tlbflush/hackbench/netperf/oltp/fio etc.

Usually we will merge all developer's git together to do performance
test.  Because there are too many developer's git.  This is the only
possible way to do test.
