No it does not - very slight is all I have ever been able to detect and that goes for the users I support too. Most of them have chosen to use it too for the great ability to just put your system back in a few moments after you encounter a problem. It is also a fantastic way to check out new software and, if you do not like it, ensure that it is completely and utterly removed from your system.

As to True Image, those I support and I are still happily using TI9. A full backup of my system disk once a month takes about 15 minutes. Incrementals every couple of days take about 90 seconds.
