heh... firstly, there is nothing inherently slow about Java3D. there are only people that are slow to learn how to use it properly :)
1) the dimensions of your objects is generally irrelevant. the relative sizes of objects and their relative positions does matter when youre having issues with z-buffering, but lets not go there. this is not your problem. leave your dimensions alone.
2) determine if you are generating a TransformGroup and/or Transform3D for each line in your circuit diagram. you should not be doing that. you should have one TransformGroup for your entire circuit.. and all the lines should be in a LineArray or something like that.
3) What are your hundreds of objects? What do you consider to be tons of memory? What video card do you have? Do you have the right drivers?
4) How are you loading this model into java3D

There is no general answer how J3D applications can be tuned. but in fact, it doesn't has to do anything with your objects dimensions. More important is the number of polygons you use and the number and sizes of textures.
Some hints for advanced tuning techniques (when possible bugs and design problems are removed) can be found at http://java3d.virtualworlds.de/j3dwiki/index.php/In_which_ways_can_I_do_optimizations_for_a_higher_framerate%3F
I am making a program which shows integrated circuits designs in 3D ... The entire universe is less than an inch....dimensions are in micrometers....how can I make the performance better? should I make the
dimensions
larger, like in meters, or should I keeop them smaller ? I have currently
been
using larger units so 1um is actually 1 meter in my program......I thought that would work....does java3D work better with small structures or larger ones...? It uses TONS os memory and runs slow for large (a hundred or so objects...) universes .... really it sucks. ... do you think it is my viewing scheme that might be inneficient....please help....
