NSSI stands for Navratil Software System Information and is an utility that provides general information about your PC and it includes a benchmarking feature to test either CPU or FPU performance. I use this benchmark on 286, 386 and low-end 486 systems.

My benchmark method


Start NSSI.EXE and wait until the program has started. Go to Benchmarks by pressing ALT+B and select CPU Performance
