It draws marginally more labels/minute (and knowing how timetext works I'd say that differency is basically insignificant) but it spends 30% more time on average per label exposed. If I'm not in total crack 1.3.8 spent 50% less time per label expose than 1.2.4 for the same test. That's what I'm worried about. > Dan > _______________________________________________ Performance-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/performance-list
