The code generated using the coder runs 2x slower!!! Please help in optimizing the speed

Hi. I have generated C++ code using the coder laptop. I have used these generated C++ source codes in my VS 2010 solution. The exe runs 2x slower than Matlab version. I have used dynamic memory allocation while generating the C++ codes. Please help me in optimizing the speed. Also I used parfor to speed up the execution but when I check the performance of the EXE, it doesn't even use more than 25% of the computational power of the system. Is openMP supported in VS 2010?

It is impossible to suggest improvements without seeing the code. Do you mean "VS 2010 Professional"?
