I watched the Felix gc. When there's a few huge lists, it is very VERY slow .. like "hardware reset" slow :) When the memory size goes past my Mac's 2G Ram it gets into paging spasms :) The good news is that even for huge numbers and pointless collections, the Felix program didn't crash :) -- john skaller skal...@users.sourceforge.net ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
