Artem, rather than throwing a fit when someone disagrees with you, why not try
to be more helpful and provide more useful info on this bug. How are you
testing multithreading mode? Are you creating a rar file or extracting one? Are
you using the command line or the GUI? What tools are you measuring CPU usage
with?

I tried wine Rar.exe a -mt2 winrar.rar foo bar baz ...

where the set of files to compress is about 500 MB. The total cpu usage on my
core 2 duo was around 120%, including running top, firefox, etc. I measured
this by running top, and I pressed '1' to display the cpu usages separately.
This was not I/O bound. The files I'm compressing are all cached in memory.
