FYI, Winrar has a built in benchmark: Tools -> Benchmark

In Wine, I get 910 KB/s. On Windows, I get ~1230 KB/s. 1230 / 910 = 1.35.

If I uncheck the multithreading checkbox, In Wine I get 745. I'm too lazy right
now to reboot yet again to find out what it is on Windows. :)

This is with WinRar 3.71. I'm using a custom compiled 2.6.24 kernel from stock
kernel.org source code. In my kernel config, I have the following settings:

- tickless kernel
- multi-core scheduler
- preemptable kernel - low latency desktop
- timer freq = 300 hz
- on demand cpufreq (I did let the benchmark run long enough that the numbers
were steady)
