I did, but using Linux+valgrind rather than cygwin+gprof. IMHO valgrind (in its callgrind flavour) 
outputs more useful profile information.
Some time ago I was able to optimize away about 20% of executed CPU instructions in the compiler, 
which however didn't decrease its execution time by any noticeable amount. So, going for another 20% 
will be a much more complicated task, beware.
