Love your videos seen every one. You have helped me alot for a long time. With my roms on xda. And various other helpful things I have learned from you. Thanks so much

OhHeyLou great video!!! Very useful. I didn't even consider changing my scheduler, don't know why, but I will now. Do you think you can do a video compiling the kernel again on Arch/Manjaro? Also could you include all the special Nvidia hooks that need to be made since I know that you now have a nvidia card (as do I) and that always seems to trip me up. Love your vids!! keep it up!!

Can you tell how we can observe the changes when we changed the scheduler ??

Hi Can you please explain how to implement any Linux scheduler to calculate waiting time turnaround time and other kind of metrics?

I can't remember if you mentioned this in video, but if I boot OS from an SSD, but also have a separate 7200rpm HDD in my second bay on laptop, is doing this and using noop still a good idea? (I actually use sio or deadline, sometimes fifo on my android device..so I'll probably try different ones here also) just curious on your thoughts with that

[AshHanna]

Can you run sudo update-grub instead of the one you ran? (If supported of course) that would give me the same result correct? (I'm very new to tweaking and using Linux. Have mostly done android hacking and tweaking for a long time now. )

And to think I installed Elementary OS because you had recently installed it again, and I was hoping to see some fun tutlage on it. I have now begun to frown most unhappily in your direction. Good video though.

[PaulWilson]

are these commands somewhere in the Notes?
