Comparisons

Spam Filters

This is a comparison of SPAM filters which I ran in April 2005, back when Mailvisa was young. Mailvisa has improved since then, as, no doubt, have the other filters. I have been thinking about running another comparison, but I haven't gotten around to it yet.

ULPS

ULPS is short for Useless Loops Per Second. It is a measure of how quickly a machine executes simple instructions, similar to BogoMips, although the BogoMips rating of a system will typically be about a factor 5 higher than its ULPS rating. In this comparison, I use ULPS to determine the overhead imposed by the runtimes of various language implementations.
