If you haven't already, try running hdparm on your drive to get an idea of if the drives are at least doing large raw reads straight off the disk at an appropriate performance level.

This is output from the little NUC I'm using right now:

# lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda      8:0    0 465.8G  0 disk 
├─sda1   8:1    0   512M  0 part /boot/efi
├─sda2   8:2    0 464.3G  0 part /
└─sda3   8:3    0   976M  0 part [SWAP]

# hdparm -i /dev/sda

/dev/sda:

 Model=Samsung SSD 860 EVO 500GB, FwRev=RVT02B6Q, SerialNo=S3YANB0KB24583B
...

# hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads: 1526 MB in  3.00 seconds = 508.21 MB/sec

If your results are really poor for this test then it points more at the drive / cable / controller / linux controller driver.

If the results are okay, then the issue is probably something more like a logical partitioning / filesystem driver issue.

I'm not sure what a good benchmark application for Linux that tests the filesystem layer as well is other than bonnie++ which has been around forever. Someone else might have a more current idea of something to use for this.

It might help for the folks here to know which brand and model of SSDs you have, what sort of sata controllers the sata ones are plugged into and what sort of cpu and motherboard the nvme one is connected to.

What I can say is Ubuntu 22.04 doesn't have some mystery problem with SSDs. I work in a place where we have in the order of 100 Ubuntu 22.04 installs running with SSDs, all either older intel ones or newer samsung ones. They go great.

1988 Nissan Skyline GT with an RB20DET.

It was abandoned by my uncle at our place when he moved overseas and subsequently my sister drove it around a bit. Eventually it leaked coolant from the water pump, overheated and blew a head gasket because she wasn't paying attention.

I was unemployed and bored and I decided to pull it apart and bought all the bits to fix it. I didn't really know anything about mechanical stuff at the time, but I am good at logic and try not to be useless at practical stuff even though I'm really a computer geek. I drove it around for a bunch of years after that until I was earning enough money that I could buy something I wanted which was a Mitsubshi EVO 1.

So to answer the question, favorite thing was that I rescued it from oblivion even though I didn't know much about cars or engines at the time.

The situation is mostly reversed on Linux. Nvidia has fewer features, more bugs and stuff that plain won't work at all. Even onboard intel graphics is going to be less buggy than a pretty expensive Nvidia card.

I mention that because language model work is pretty niche and so is Linux ( maybe similar sized niches? ).

The samsung TV that I bought for my son had this annoying overlay thing that pops up when you turn it on that shows all the different inputs and nags about various things it thinks are wrong with the world. It is plugged into an Nvidia shield that we do most things on, but you can't use the shield until the overlay calms the fuck down and disappears.

It'd be great if you could just have the thing turn on and display an input like our older TVs do.

This damnable prison of log and ice eats away at my fibre. I find the lack of culture astonishing.

Agreed, it seems like they should have put just a little bit more in the standard feature set so every little window manager doesn't have to reinvent the wheel.

I learned what a tankie is, which is fun.

I've been commenting a bit, whereas on reddit I would only post a comment a few times a year when I could be bothered dealing with the likely burst of negativity that would come as a response to it.

Kind of feels a bit more like Web 1.9 or so from about 2003 which I think was about the sweet spot for minimal rage bait and crazy and still a decent bit of user interaction and scale.

It would be about perfect if you could chop out a few of the folks trying to shoehorn in politics to every little thing.

Appreciate the reply. Which desktop environment are you using?

My only experience with Wayland is also with KDE. Wheres for the 27-ish years before that I've used all sorts of stuff with X.

I've scripted the machine that drives the frontend for our video surveilance ssytem to place windows exactly where I want them when it comes up.

I use a couple of dbus triggers that make the TV on the wall in my garage go to sleep from the shell, perhaps not tested via ssh though. They were pretty well the functional equivalent of some xset dpms commands that I used to use. Not sure if that is what you were meaning. I think I also had something working that disabled the output altogether. I think that was pretty clunky as it used some sort of screen ID that would occasionally change. Sorry I'm hazy on the details, I'm old.

I'll try it all out when I get home, I've got to find some old serial crap for a coworker in the garage anyway.

Which workflows? Asking because I'd like to experiment with some edge case stuff.

I'm running KDE with wayland on multiple different vintage machines with AMD and intel graphics and it would take alot for me to go back to the depressing old mess that was X.

The biggest improvement in recent times was absolutely pulling out all my Nvidia cards and putting in second hand Radeon cards, but switching to wayland fixed all the dumb interactions between VRR ( and HDR ) capable monitors of mixed refresh rates.

Even the little NUC that drives the three 4k TV's for the security cameras at work is a little happier with wayland, running for weeks now with hardware decoding, rather than X crashing pretty well every few days.

Last week I did an install of Debian 12 on a little NUC7CJYH to use for web browsing and ssh sessions into work and ended up with wayland by default. Seems to work great.

From what I have experienced, it goes great with intel integrated graphics, great with a radeon card and can be made to work with Nvidia if you are lucky or up for a fight.
