I’m not advocating for anything but for distros to stop recommending swap partitions. I advocate for right-sizing your hardware to predicable workloads and not using swap at all. On your pet servers or desktops where the workload is experim

This is a mechanism post not a policy post. If you want to see my take on swap, see my last response on that gift.

Swap is not recommended on servers where responsiveness and determinism are more important than failure recovery of any one server.

I love this kind of stuff. Great share

Looks like this was added in util-linux 2.40. Works with btrfs correctly too! Added.

This recommendation is based off the current implementation. See: https://github.com/torvalds/linux/blob/827751b699b79a6e56998... https://github.com/torvalds/linux/blob/827751b6

+1. This test and its conclusions are flawed. See CAV/CLV

What subsystem are you referring to?

I wrote this years ago before LLMs made it easy to validate guesswork. I’ll update! Good call

>> ZFS is overrated and mostly a hobbyist/enthusiast thing. Not true at all.. but most large object storage redundancy has moved to the application layer. There are still workloads that are a great fit but I agree OpenZFS is curr

Not a btrfs user but OpenZFS u til recently didn’t even support O_DIRECT and may still duplicate page cache in arc. It’s not well suited as a general purpose FS where you can’t anticipate the workload, like on a desktop.

Agreed. Buy more RAM but these days that means taking a HELOC

Truth be told—- I don’t use swap and set `vm.swappiness=0` but in these difficult times, swap may be the hero we need.

by jenders 6d ago
That’s a good call out. I’ve never used ZFS on root. Been a ZFS user on Linux since the FUSE days but it has never seemed particular well suited (O_DIRECT support came late, ARC/page cache redundancy, etc). I can’t guarantee a consiste

How often are you needing to change partition geometry after install, on a server?

If you want to share step-by-step, I’ll update the gist.

If you like that abstract geometric headline image, you might also like the source artist their model “learned” it from: https://leegriggs.com/xgen-rendered-with-arnold-for-maya

Context: spent my career building CDNs at Cloudflare/facebook/pinterest. The h3 juice is worth the squeeze. 0rtt TLS, BBR, HPACK, etc. You can roughly achieve this with a carefully configured h2 deployment across multiple layers a

Seems like the major gripe is over my usage of the word “obsolete” instead of “deprecated”. We could all be flipping switches instead of tapping on MacBooks but you gotta draw a line somewhere.

Agreed! I love naming things :D

Yep. All HTTP/2 features are subsumed by HTTP/3 and all HTTP/2 deployments should be focusing their effort on moving to HTTP/3. HTTP/2 is full of growing pains and fiddly kernel config for it to perform better than

I would been pleased to see this project named something else, maybe “httpx-ng” or “httpy” as I immediately link “http*2” with the obsolete http/2 protocol and not the httpx project.
