NUMA NUMA make Raspberry Pi go ZOOMA

Raspberry Pi 5 gets 10-15% speedup with 100 line Linux kernel patch. And what if we could save 50 megawatt-hours of power annually, just with a software patch for older Pis?

I'll walk through the NUMA Emulation patch that supposedly boosts Pi 5 performance, as well as some other new performance-related developments coming down the pike!

I keep hearing some 20-ish year old pop song when reading “NUMA NUMA”…

Wholeheartedly agree with the kernel maintainer. This should be fixed in the firmware and not with some fake NUMA hack that adds eternal technical debt.

My favorite blooper was "Raspberry Cake"

petition to have these epic oldschool thumbnails from now on.

[sevendaysin]

Please keep the outtakes! Funniest way to end every video =)

[Sam-qnly]

lol, love the thumbnail. the video should have been uploaded in 240p to really fit the vibe :)

Thank you Jeff for bringing back the bloopers! Such a pleasure to watch your videos. I’m sure they are, but I hope the Raspberry Pi Foundation is watching.

If You didn't know, your channel had been categorised as a server channel by YouTube.

Now everytime I watch your videos I get recommendations for home server videos. Alongside yours.

The outtakes make me laugh. Glad I'm not the only one who trips over their words.

NUMA stands for Non-Uniform Memory Architecture. This was already used in supercomputers.

Thanks for the blooper reel again. Love it

[frankbohnen]

Every Sunday, I look forward to your videos. Always so informative. Please, more bloopers at the end. It makes it even more joyful to watch and shows how much effort goes into making these videos. THX for creating all this contends.

I know this is totally irrelevant but yesterday I ate the best orange ever

[Neilhuny]

Absolutely fantastic video! Surely no-one else packs so much information in to such a small footprint. There is a week's worth of testing, playing, checking, reading and (mainly) head scratching in this video. Most of your videos, tbf

[syrusk]

Sleep states can be super useful if you're doing battery powered Pi stuff!

[anneallison]

Jeff I began watching your videos just before the pandemic and I can tell you after all this years I finally understand everything you say. You are gold!

[michaelreed]

Happy to see the bloopers back :)
Thanks for the continued great content!

[mattybbg]

A doff of the cap to you and your 100% accurate shirt sir!

Your content just keeps getting better and better.

"NUMA NUMA" 👍 Interesting look into some issues, I'll have to remember these as they get fleshed out.
