Traffictools itself doesn't impact frame rates, it's the planes you add with it. I recently added a AA 732 which would show lately, was a killer on frame rates, so i replaced it. When i add new planes i usually take them out to a lone airfield somewhere with no other traffic or anything and then check what kind of frame rates i get with them when just letting it sit on the rwy. Then i compare that to the default AI planes and if it differs to much, the new plane gotta go.
