Limit ISO Write Speed in Build Mode in ImgBurn Suggestions Posted August 16, 2006 If you wish to ifree your process, perhaps set the app to below normal priority. That doesn't help. Even if I'm not doing anything processor intensive, other programs will become slow to respond. And this is with multiple drives, not copying to the same drive. There's no way to limit the speed unless it gives you the option. I guess I just won't use this feature, since it takes away my computer's functionality. I have 1.5 GB of RAM and lots of free memory. If the program wants 100% of my hard drive time, that's too much.
