MCL's view system was not designed for huge numbers of views.
As Karsten Poeck said, you may get better performance if you add
some hierarchy to your views.
Quite a while ago, Alan Ruttenberg and Dave (whose last name I have
forgotten) implemented a quad-tree extension to MCL's view system to solve
just the problem you're having. I don't know if their code still works or
if they are at liberty to release it. Alan?
