[Qemu-devel] Best way to get real performance info?

[Alessandro Corradi]

Hi all,

I need to measure the performance of a host OS, a guest OS with and without kqemu.

I particular I need to have performance info about CPU. I made a simple C program that makes only arithmetical operations and long cycles.

I run "time ./myapp" but the results are not the real ones. Can someone tell me how to get this measures?

Thanks
