I made up three tests: repeatedly drawing one of several things, running
geomview with a fixed window size, etc., and using geomview's internal
clock to report timing.

You can pick up priv/slevy/geomview-speedtest.tar.Z from geom.umn.edu
to get the tests and the results gathered so far.
to get the tests and the results gathered so far.  I've gotten one report
from someone with a Pentium machine; here it is compared to our '486 machine:

# Tests: "polygon" : 1620 small flat-shaded LIGHTED polygons
# 	 "matrix"  : 30 vectors x 115 matrices
#	 "tmesh"   : flat-shaded LIGHTED tmesh sphere: 35 rows of 70 tri's
#			(Uses tmesh primitive on SGI; other platforms just
#			 draw 35x35 quadrilateral mesh)
# All tests in 200x200 window; all polygons are flat-shaded and LIGHTED.
# Times are milliseconds per test cycle.
