Workspace creation

Hi Team,

What are the pros and cons for creating workspaces when we already has the system setup and using for years.

Currently we are using "Default Workspace" created by marketo and want to create more workspaces now as per the regions. I have 2 main questions here:

1. Will it improve the system performance regarding to any lead related activity i.e: lead import/export, Lead sync etc

2. Is there any impact on other things as we already have setup system and using it for years.

Thanks

Saurabh
