kern.sched.preemp_tresh

[mer]

So what does kern.sched.ule.interact actually do? And why does setting it to 0 or 100 'largely "turns off" any impact from interactivity-scoring' ?

So if setting to 0 means nothing is interactive and 100 means everything is interactive, then my understanding is "if everything is equal, then it doesn't have any effect".
Like when your boss gives you 12 tasks you ask "which is highest priority" and the answer is "they are all the highest priority": that tells you none of them are the highest priority so you just "pick one" and start working on it.
