The following measurements are derived from benchmark code published on the Smalltalk Industry Council site, under 'Benchmarks'. Code is available here only so that anyone wishing to reproduce the measurements may do so readily in the various images.
Tests were conducted on a 166MMX Pentium with 40MB RAM, under Windows/95 OSR2. Each test was run three times.
