I've got a multiprocessor machine. What exactly do I need to do to test this stuff? I haven't been following the entire thread. I should... ./configure --with-mp=yes Then do make and make install correct? Then what??? Just use gimp or do something specific to test. I think SMP optimization is important. The future of Gimp depends on it. we want Gimp to dominate on that new cube from Sony with 64 PSX2 processors. 8-) -- Jon Winters http://www.obscurasite.com/ "Everybody loves the GIMP!" http://www.gimp.org/
