I decided to run some benchmarks via Norton Utilities System Info 3.2.1 (System 7.0.1) with the original clock chip and overclocked to 25Mhz with 50Mhz clock chip, with and without the card/cache and FPU:  
        A neat progression in performance improvement (essentially doubling over stock). The best performance run “Macintosh IIsi/25 + FPU/Cache/D” came when I remembered the Memory Control Panel Disk Cache trick of setting it to 1024k to use up the slower soldered on motherboard 1MB of RAM with disk cache forcing the video memory, OS and all other apps to use the faster RAM in the SIMM slots. If you have the memory a pretty significant improvement on its own!    CPU comparison with the other system in this version of Norton Utilities System Info:
