Poor performance of parts with patterned entities

What will improve the performance of parts patterenedentities? Will processor speed alone do this? I have a part with asimple, a very simple vent slot pattern that takes forever torebuild, in fact sometimes it crashes the system. This is on a 2.8Ghz single core machine with 2GB of ram. Is there some other trickto this?SolidworksAdministration
