My eee shows something like a 2x increase in speed in the planets script that Stu sent to the list some months ago. if you feel like trying the new code, get it through hg clone http://bitbucket.org/rlafuente/shoebot-filestructure the script i mentioned is in examples/basic/transform/planets.bot (in the main branch it's in examples/nodebox/transforms_stress_test.bot IIRC) can any of you guys test it to make sure i'm not seeing things? :r _______________________________________________ Shoebot-devel mailing list [email protected] http://lists.tinkerhouse.net/listinfo.cgi/shoebot-devel-tinkerhouse.net _______________________________________________ Shoebot-devel mailing list [email protected] http://lists.tinkerhouse.net/listinfo.cgi/shoebot-devel-tinkerhouse.net
