Actually if you figure at 10 bits/byte you'll get a much closer estimate of true maximum speed. On a 512kbps link you'll rarely see more than ~ 51.2Kbytes/s even on download tests, similarly ~150Kbytes/s @ 1500kbps. So 33Kbytes/s is closer to 64% of maximum, and as you say is not unusual on a heavily loaded site, or over international links. K being 1024, of course, which is what fetch reports, with k (bps, bits/s) being 1000. cheers, Ian
