Sometimes the HR20-700 can be sluggish, other times not at all. I few weeks ago I did the red red blue blue yellow green thing and it has been overall better. Whether that is related or not I don't know. I also now have a SWM setup with MRV as of a few weeks ago, so that aspect in my setup has also changed. I meant to ask earlier - what info (and what is the related functionality) is stored in the NVRAM?
