AFAIK fpc does not differ that much in speed compared C on numerous points, there are benchmarks out there. So my suggestion would be to try to optimize your code as much as possible (in my experience if you look very critical and do a lot of tests you will see you can increase speed significantly). If that does not help you can try asembler that you can inline in the pascal code (platform specific, but thats the reason why its optimal). C code can easily used within pascal written programs by using libraries. Check the wiki for more information. There are also pascal math libraries which you may want to checkout: fpmath and JediMath, but these are generic so not highly optimized.
