Unhappy Help with lag! (Trim)

I got a new Nook HD+ in June. I kept it on stock, until about October, when I flashed cyanogenmod 10.1.3, then 10.2. The lag slowly became worse and worse until it was almost unuseable. I finally found a thread saying to format data and datmedia, so I did. This fixed the lag, but it started to come back. This is almost certainly a trim bug, but I know almost nothing about that (I am in middle school ). I do not want to format again, so I don't know what to do. Right now, I am on cm11.

If you are on CM11 then trim is enabled so it will run when certain conditions are met. I have found the easiest way is to plug it in overnight. Trim will run if the Nook is charging and has been idle for a period of time. Hope this helps

Thanks for responding. I had daydream on, so I don't know if trim ran or not. It seems like the lag is slowly getting better, but that may be the placebo effect. Is there a way to see if trim has run or is there another way to run it? Thanks!

There is a command line that can be run in Terminal that will check the log of the last trim run. I used it once to be sure trim ran BUT i do not remember the command. Do a search of the forum and you will find it.

I'm sorry, but I can't find it anywhere. Could you find it?

On that thread, I found instructions to run trim manually from Terminal. I did it and my nook was a little bit faster, but still significantly laggy than it is supposed to. I have started to think that the lag may not just be trim. Could this be true? Also, I ran Androbench and my random write was only .11 mb /s.

Also, I have the MAG2GA chip. Will this affect the speed of my nook?

When I run trim from the command line, it always says that it trimmed the same number of bytes each time, even if it is just a few seconds after. Is it supposed to do this?

Thanks again for all your help!
