@cadusilva@bolha.one Se o comando for personalizável, deve conseguir diminuir a prioridade geral do processo e também quanto a entrada/saída, por exemplo:

nice -n 15 ionice -c 2 -n 7 comando

Ver manuais de nice e ionice :debian: :podeConfiar:

Porém, a efetividade da priorização de I/O também pode depender dos algoritmos de escalonamento definidos na máquina ou para cada dispositivo de armazenamento. Se quiser conferir várias minúcias, vale a pena estudar esses detalhes. 🤓

Benchmarking: BitAxe Gamma 601 und NerdQAxe++

Um die Benchmarks der beiden Open Source Solo #Miner BitAxe Gamma und #NerdQAxe++ zu optimieren, gibt es die Tools #Bitaxe Hashrate Benchmark (ein Fork der Arbeit von WhiteyCookie: Bitaxe-Hashrate-Benchmark) und den darauf basierenden NerdQAxe hashrate benchmark. Mit den beiden Tools entfallen zumindest die manuellen und zeitraubenden #Tuning Vorgänge, da beide Tools nach den Benchmarktests jeweils die auf #Effizienz oder Geschwindigkeit optimierten Einstellungen anzeigen und die letzteren automatisch auf den Minern speichert.

"Our universe is pretty rare in configuration space - if strong nuclear force were:
* 1% weaker - stars wouldnt make much carbon preventing carbon based life & less heavy element production would delay planet formation & take longer for evolution to occur before stars die
* 1% stronger - stars wouldnt make much oxygen preventing water/earth based life & stars burn faster shortening the time for complex life to emerge"

Eine Studie zeigt: Wer sein Auto extra laut macht, zeigt oft sadistische und psychopathische Züge – nicht nur Narzissmus. Vor allem junge Männer mit solchen Vorlieben wollen andere erschrecken oder stören. Lärm als Machtspiel. (Artikel ist vor einem Jahr erschienen.)

Hmm, perhaps something like this running TunerStudio would be useful when doing pulls and adjusting maps. Much less bulky than a laptop on your lap or in the passenger seat.

No comment on the PITA factor!

That said, was toying with the idea of making my garage "Artoo" unit mobile on wheels and batteries for moving to the cars instead of moving the cars to the computer, or using a laptop.

Future project to mess around with perhaps.

Ok Fedi. I am looking for an archive of all the deleted Cobb software and maps.

If you only have the ones for an 04 WRX, that's fine, but I've been digging around the bilge of the internet for a week now with limited success.

If anyone has a complete archive, I want it.

Zacznę od aktualnie zakończonego projektu który przechodzi tylko małe modyfikacje przed sezonem. Otóż jest Nissan Micra K11. Silnik, seryjne 1.3 ale dopreżone na tłokach z 1.0 z ostrymi walkami, układem zapłonowym przerobionym z aparatu na cewki, wtryskami z golfa R, dodanym rollbarem w środku i wieloma innymi modyfikacjami uwzględniającymi układ dolotowy, wydechowy, paliwowy, elektryczny...
Auto stworzone tylko dla zajawki i chęci zrobienia czegoś po swojemu. Jak wyszło? Obserwujcie kanał i przekonajcie się sami. Auto będzie wystawione na wielu pokazach w całej Polsce.

With CachyOS, and Linux sched-ext feature, you can choose any one of OS schedulers in BPF. That way you can optimize your system further based on workload; some good for LLMs, some good for high-network services and so on. (There is even a GUI for this). See wiki.cachyos.org/configuration

Linux is the only operating system that provides such flexibility AFAIK. If this is available in other OSes (desktop or server), please let me know.

A scheduler in an OS kernel is the mechanism which coordinates the operation requests. There are a collection of them where one may be good with video games, another with databases. There is no single 'perfect' solution.

That should be good. Next things I would look at is tuning your postgres and nginx. Thsre is a good writeup on this, but I can't find it currently.

There is always a bottleneck. You just have to find it.

Rule #1 of performance tuning: Only change one thing at a time, and then monitor.

If you change multiple things at the same time, and it gets better or worse, then you will not know what helped or hindered.
