App Tamer 2.0.1 corrects a few issues that were causing slow-downs in App Tamer itself, especially when it first started up. If you had an application that had a lot of sub-processes (typically Terminal, Google Chrome or Safari), App Tamer’s launch time could be glacially slow. And even after startup, pausing and un-pausing those apps took much more CPU than it should have.
In addition, CPU usage was reduced in several other areas and several bugs were squashed, including one that could cause App Tamer to fail to reenable itself after you turned it off for a specified amount of time.
