A faster way of opening your work shared project is to specify what worksets you would like to open during the file opening process. That way you have total control on exactly what will be visible, and not have to load any information that is not required for you current requirements.
Select the workshared projects you would like to open, then select the down arrow beside the open button. This will activate the Workset options where you can select the worksets you would like to have activated.
Specify is a great option for individually selecting the specific worksets you require, it is also a great choice for file maintenance where you can choose to have no worksets open so the file opens a fast as possible.
