In order to estimate the kind of performance gains we can achieve using dynamic transalation, I'd like to run some small benchmarks without the overhead of the operative system. If i understand you correctly, you want to try qemu-user. Beware that when benchmarking, qemu-user should probably be faster than qemu-system, as it doesn't have to emulate the os and hardware. Marco
