Linux Process Tuning Made Easy: Understanding nice and renice

[@SnowDaemon]

Seriously this channel is the best. The amount of free knowledge available is wild. Thanks Jay!!!

I love your series Jay! You have a tallent of putting valuable information into easily digestible form. I like to rewatch them every couple of month to brush up what I've learnt.

Great video! I would’ve loved a quick explanation on what process priority means in practice, and what its “niceness” means, though, before going into the “hows”.

I'm a huge admirer of Jay; I've been watching his videos since I began learning Linux. Thank you!

....and a happy new year!

Jay, can you make a video on why and how to track different logs files to diagnose different things? Thank you.

[@synen]

I appreciate the video. However, as beginners we need practical examples on when to do this, lower or higher.

thanks Jay, great video :)

Thanks a lot. Your videos are very interesting and easy to learn. Request you to add more videos on BASH scripts and LXD.

It would be nice to be able to adjust the priority of a vm (instead of a process) in proxmox..

you are the best in linux OS administration

Outstanding video and great description of nice and renice. It's very confusing the way nice and priority values are counter-intuitive, but you presented it well so even I can understand. Question - if I change the nice/priority of a process with sub-processes, will this change automatically for the sub-processes as well? Eg: I'm running Kdenlive and the rendering engine uses the process named "melt" with dozens of sub-process. Do I have to renice them all, or the the top one?

Hi, i think it will be good to cover FRR (free range routing) as a topic for your channel. Best regards

Hi, what is the name of the terminal font in the video?

Pretty sure nice doesn't go to to 20. You said that several times. -20 to +19. Those plots the zero in the middle make a nice round 40 levels.

Very (re)nice!
