Same. I tried some, and even in games they didn't provide much of an improvement. Sometimes performing worse, even. I just put some niceties like irqbalance and add a few lines to sysctl.conf for better latency at a cost of throughput (doesn't matter if you're just using the system as a desktop and not as a server). And that gives me a very nice experience overall. Edit: Please, be careful. This is under a very well…

How do you improve the latency? Especially reacting to mouse and keyboard, I have an old PC which could use that.

Oh, I was mostly describing network latency and file IO cough should apply to mouse polling as well but bear in mind what another user has said. For mouse specific concerns, I would take a look at the following tutorial:

Best of luck!

By decreasing latency, you decrease throughput. Thus if you have a slow and old computer, you could end up dropping inputs entirely by decreasing latency, or make it feel sluggish/laggy due to it processing a queue.

You're correct, I should add something to my post.

For older devices, the most gain would probably come from using a lower resolution input and a lower resolution output (to match what was available at the time). Throwing a 2k monitor on a graphics card from 2014 is probably going to be a barely passable experience (buffers weren't as big back then), same with mice.

Wait, wtf. There's this in addition to lanzaboote? But no mention of it? (And at one point there was another new list with bootspec support, maybe still is) Please, people, if you release software that overlaps or competes with another existing in the space, take the 3 minutes to write a comparison note or "why this exists". Please.

Why should any project have to justify it's existence? Maybe it just scratches an itch?

I mean, at the very least, I do this because I make/release things because there's a gap to fill or an itch to scratch. And if I'm releasing something it's because I'm hoping it will be useful to others.

It seems like a natural conclusion to spend a fraction of the energy to author, to detail it's reason to exist.

Anyway, no one owes me anything but I trust that Determinate Systems has a grander vision than I can see, I just want to be clued in, to be honest ;).

If I wanted to keep Secureboot enabled, would signing with a MOK and enrolling that key be sufficient?

You say that as though it's easy. I've yet to find an explanation that's shorter than a book.

Maybe I need to write it a little more clearly, but perhaps that will get you there.

Thanks! Curious, why changing network/disk IO latency, does it help in online games noticeably?

It does, even when navigating the web.
