Vision over 100 clients will probably have more of a performance penalty on the gateway than Perspective, due to the less efficient polling architecture.  
Perspective sessions, due to their backend component running on the gateway, do have a higher _initial_ penalty on the gateway (ie, 5 Vision clients are likely going to have less impact than 5 Perspective sessions) **but** Perspective sessions scale much, much better - the impact is basically linear.
