Here are some sample timing results obtained using the trunk version of ggobi on 17 April, 2006; red hat linux. (ggobi -t foo)

data/laser.xml
TIME(init) 0.12 msec
TIME(brushing) 52.43 msec
TIME(tour_default_variables) 15.88 msec
TIME(tour_all_variables) 29.02 msec

data/olive.xml
TIME(init) 0.10 msec
TIME(brushing) 41.73 msec
TIME(tour_default_variables) 26.44 msec
TIME(tour_all_variables) 25.57 msec

data/places.xml
TIME(init) 0.11 msec
TIME(brushing) 37.58 msec
TIME(tour_default_variables) 25.40 msec
TIME(tour_all_variables) 25.75 msec

data/prim7.xml
TIME(init) 0.10 msec
TIME(brushing) 45.68 msec
TIME(tour_default_variables) 29.76 msec
TIME(tour_all_variables) 29.97 msec

There's some variability, of course. Here are four sequential tests for big100x10.xml.gz
