[boost] C++ Performance

Hi everybody Im a quite new boost user and I wonder, why C++ Program is so slow. I wrote a program, and I have the same program in Matlab, I expected that my C++ version is much faster, but its not. I use matrices, vectors, matrix- and vector proxies. Do some solving and compute calculations with prod, element_div, etc.. Is boost in general slower than matlab, should I use something else? Id be real happy about any help.
