After installing KeepSafe 2.0 a week ago, not once has it ever let my system use less than 50% of my cpu. This is no fun as it make loading large VS2005 projects even slower. I have let it run overnight several nights in case it is busy with something... but it just lags the system. As soon as I choose to unload KepSafe, the cpu is freed up and the machine springs back to it's snappy self.
