This is very basic for any self driving car system you can see on the road today or even 10 years ago.

yeah, this will definitely shorten the lifetime of an nvme. but check my other comments, it makes a difference, even on a slow nvme. Probably the overhead of the wasted small extent, and maybe prefetching?

check my other comments with numbers, while small for a human being, I could see the variations benchmarking copper-rs.

My observation is that it is not completely true. I constantly have a close to full partition in ext4 and there is no secrets when there is no space the filesystem WILL create a bazillion of small extents because, it has no physical choice!

What actually triggered me to do that was to be able to test repeatably my other open source project in rust were the compile target directory can go to hundreds of gigabytes of files and at the same time I need to benchmark it on large lin

Yes: I discovered that tested performance on copper-rs a high performance OS for robotics when I run it on ext4 and what is annoying in robotics is the max latency & jitter. Especially that we allocate large slabs so this is not helping

This is true if you can scale out (ie you can add resources to your system). But for a robot for example, just adding a GPU can just flop your product completely: you need more battery, more weight, suddenly your unit economics is out of th

It is more like a "design by committee" issue to me. The decisional structure needs to be built for some opinionated decision. When you have a committee there is not one clear thing they are solving for as everyone has an agenda t

Yes and honestly super kudos to paru's creator for the nagging warning about installed orphan packages that made me remove them immediately. So with a dozen of various systems running arch/cachyos for various purposes, 0 impact. W

I don't think it is surprising. Loading entire chrome processes for simple super laggy UIs is just unbearable. TUI are snappy, accessible over ssh, small screen friendly, easily embeddable in zellij or other multiplexers, easy to copy
