Qemu accelerator kernel module

Last week I tested the new -controversial- Qemu accelerator kernel module.

These are the results of the nbench2 benchmark:

Using the accelerator kernel module:
integer: 4.940
floating point: 9.813
memory: 5.994

Running the test on my machine without any emulator involved:
integer: 5.693
floating point: 11.083
memory: 7.137

Quiet impressive imho... of course -just as with VMware- as these "emulators" actually just execute the assembly code, they should approach native performance. It's a whole different story when IO-bound applications are benchmarked.
