Odd Benchmarks

A simple benchmark where one tries to set a value in a CLOS-object and in a hash-table, compares how much time this takes. The source may be found at http://www.ii.uib.no/~stig/set-speed-lisp.tar (The benchmark was doen because I was uncertain of whether to use slots or a hash-table for an application).
