My short answer is, no it should not be significantly slower from the
perspective of the processor... In my experience.

Longer answer:

A few months back I did some speed comparisons between some code I wrote
running under Windows, coLinux and native Linux.  The program was a snippet of
some AI code doing a mix of int and float math using linked lists and arrays.

In any event, here is what I saw (qualatatively):
  - code compiled using intel's C compiler ran at pretty much the same speed
under windows, coLinux and Linux. (dual boot machine) Other than the initial
load of the program, there was no disk i/o.    The variation in run times was
only a couple percent at most.  
  - also, code compiled using gcc ran at about the same speed under native
Linux, coLinux and Cygwin.  These did run significantly slower than the intel
compiled binaries.   

This testing was under the 2.4 kernel.  I have since moved to the 2.6 kernel
but haven't seen significant slowdowns.

As a side note, coLinux provides a nice way to run the free Linux version of
Intel's C compiler under windows.  The speed benefit over gcc CAN be HUGE for
certian types of programs.
