Switching back(wards)?

Most of my code for doing brain-wave recognition has been written in C++. I spent a lot of my time making beautiful objects incorportating FFTW, valarray and Lapack (via the Sun Performance Library). Though I wrote to opimize code reuse - things are just getting to be too complicated. Over the last few months, I've read a number of articles talking about how Matlab now uses FFTW and Lapack... perhaps it is time to switch back? Before I did, I wanted to check on timing... shouldn't compiled code be faster? Incidentally, time consumption in my code is basically in the linear algebra, so if Matlab uses the same libraries... After a bit of searching, I found a very useful article entitled "Timing Comparisons of Mathematica, MATLAB, R, S-Plus, C & Fortran".
