Browser & TC10 Very Slow During Recording

I am creating a test where I go to a web page in Chrome 44, navigate around, then close the browser. When I record, TC10 runs very slow. Many times, it just hangs/crashes and I have to kill it through task manager. 

It is also very slow if Chrome is open and TC is open, and I'm in TC changing an action from Keys to Set Text for example.

I can only use Keyword tests. 

Does anyone have any advice?

Thanks,

Heidi
