Cool but why? Isn't the software platform the sole point of Amiga?

For some people, when you are not taking over the whole machine (as you would do in demos and games), then replacing the OS with something that gives you memory protections and virtual memory, uses all ram for caches, talks ipv6 and things like that is kind of neat. It will be a somewhat slow unix box, but it is still that same machine doing both kinds of tasks for you.

Make your post relate to my post. Your statement currently does not.

It does, you make certain claims in your text, and the parent questions how to test you alternate theory against the perceived reality to see which of those two are true.

If you are writing HelloWorld-webscale daemon from scratch, then counting +lines is probably "ok", but considering some existing large project like Linux (for instance), you would be well off keeping people who has managed to retain functionality while removing lines. Old projects have a tendency to get a lot of old cruft in which tends to stick (chestertons fence and all that) but someone clever enough to rewrite and remove old useless code is a net win for you, so I agree that if you fire some percentage on most-committed-lines you either had a very recent project from scratch or the measurement is stupid.

How can we make programs this slow in 2025 when people have ssd and nvme drives, people have 12-24-64 threads in the cpus, memory that is lightning fast and still we wait for crap to load? How is it that noone creates pushback on applications being this bad in the first place? We get to read articles on how someone made something 10x faster, but seldom anyone complaining about it being 1/10th of decent speed to begin with.

I think it was MS Access 2.0 that had some text on the back about being up to 100x faster than the previous versions, and to me that reads as "old was crap as hell", but some marketing person thought that was a super quote to put on the packaging. Perhaps it works, perhaps not.

I think I would not. When you move from 160x200 with few colors to 4k with 16M colors it places new demands on the graphics which I don't think this solution would give you. It could, but would probably require tons of people to make it happen.

Lets take the pilot walking at the start of Raid over Moscow, it was super well animated and designed for the sprite limitations a C64 has, but I am not so sure it would be upscaled to represent a walking pilot, since some of the oddly placed pixels might grow into something vastly different.

And another example, AI upscaling the C64 version Dragons Lair will not turn it into the amiga version, or the laserdisc version. ;)

> I am not so fond of those fsck and lost data we used to have on an occasional basis after an unexpected hard shutdown due to a power cut in the 90's.

Yup, still the case today.

Currently with an SSD, when there’s a power cut, there’s about a 20% chance my router will require me to walk downstairs and plug in a keyboard, type “fsck” manually and press y at all the prompts.

I haven’t actually had any issues with noticeable data loss though.

I’d settle for a default “boot anyway, press y for all fsck questions” mode on boot. I just don’t want to have to physically touch the thing.

Look up where fsck is run in /etc/rc and add the -y there.

Is there a cheap SBC in which it runs without hassle? I would like to give it a try. I've used Freebsd from 2000 up to 2015 or so, but never used openbsd
IcePic · 2 months ago
If you can get an Edgerouter Lite 3 it will run fine() on that, serial console, three gig ports, fanless and not-x86 and probably available for cheap if you look at used hw sites.

) as far as its hw goes, that is. Will not be competing in speed competitions, but cheap SBCs just never will, do they?

Has anyone benchmarked TCP performance now that it's outside of the global kernel lock?

I wonder how useful this will be for the modest but still multicore systems used for firewalls.

IcePic · 2 months ago
Yes, at http://bluhm.genua.de/perform/results/perform.html (a bit down on the page) which was also mentioned during bluhm@s talk on EuroBSDCon 2025() recently.

Then again, the sentence "tcp is outside of global lock" is very generalized, there are so many parts that got out of the kernel lock in pieces, like ip input, routing lookups and device packet handling that it is hard to talk about it as one singular thing that you just flip a switch on to make it MP-performant.

You could make filesystem code mp, disk device drivers mp and then still run on an IDE-disk which forces all IO to be one at a time and serialized first-come-first-served at which point all the work was for 'nothing'.

Same goes for networking, there are many many layers and places that all need code that actually allows for MP processing to improve its performance, fine grained locks (which reduce perf at this stage), then prove that the fine grained locks are sufficient for ALL use cases, all kinds of layering violations that could possibly happen, then you can unlock this single layer, and move to the next if nothing acts up on any machine.
