To boost solidworks/smarteam performance, perform the following steps :
1. Open system configuration editor utility (Start/Programs/Smarteam/Administrative tools/System configuration editor)
2. In the search field, type "Solidworks.TRACE"
3. Click on "Add value", Select "Domain" override level and add "FALSE"
4. Save changes.
I have noticed significant performance boost when smarteam integration starts with the above setting.
