Here is a useful number that may help your now-famous web page out: The mean file size in ZDNet's WebBench (you can download the benchmark from their site, if you wish) 10342.3 bytes, or 10kb. In other words, the "lesser" Linux box can handle a bandwidth of 107 Mbps, and the quad box can handle a bandwidth of 150 Mbps. - Sam (kiwi-6hu34ln@koala.samiam.org)added @ 3:38 EST jun 28, 1999.
