turbo-boost

In our application we have many versions of the same routine optimized for different kind of processor architectures. During install we run performance tests and select the best version of routine.

Latest processors can boost their frequencies if few cores are in use, so sometimes our tests peeking wrong version of routine. Is there some way to temporarily turn off Turbo Boost?
