audio codec on the virtex-ii pro board

Is the audio codec on the virtex-ii pro board a good choice for real-time audio processing? I designed an application that reads the ac97 input in PPC, filters signals in the fpga, and then plays them back to speakers. I compared the real-tim performance between my design and having everything done in software(PPC), and it seems to me they have similar execution time. I was hoping that by using the fpga for the filtering computation, the overall speed would improve. This is true when I only measured the part where the computation is done, but not for the overall execution time (read/write ac97 and filter signals). Is it because ac97 I/O slows down the speed? Does this have anything to do with the limited bus speed (100Mhz) between PPC and fpga? I'd appreciate for any pointers. Thanks!
