benchmark console (b-co) runs a small console benchmark. The benchmark consists of printing characters, scrolling and cursor positioning. The result is printed to stderr in units of charaters per second. The same program can be used to benchmark pipe throughput by issuing "b-co!wc".
Sample results:
b-co: 1250 (pal C64), 1686 (pal C64 with REU)
b-co!wc: 816 (pal C64), 910 (pal C64 with REU)
