Pros
Easy to set up and use program control is fantastic, ability to easily see what is slowing your machine and make priority changes all in one screen.
Cons
Free version is limited and gets more so over time, features become unusable. Fairly aggressive attempt to get you to buy. Free version does not seem to hold settings indefinately.
Summary
This program allows me to tailor the way resources are allocated on my machine. I would most likely purchase if there were multiple installs, and if I was more confident the pay version would not lose settings like the freeware does. Overall a great idea.
