Visual Paradigm for UML Very Low Performance


I use Visual Paradigm for UML 6.1 SP1 professional edition on my project.
In my project i have 18 Use case diagrams and 16 Class Diagrams and 10 ERP Diagrams. Size of my Project file is 2,6 MB. I have Windows Vista 64 and 4GB Ram.
When i open project Visual paradigm is very slow. Saving of project takes about 1 minute, switching diagram tabs is very very slow (20-30 s),…
Memory usage is on start about 250 MB, during work about 600 MB.
I try open project on windows XP and situation is the same.
Where is the problem? Is performance of Visual paradigm so small?
