Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Where to get spare side panels for Intel NUC 9 Pro

Could my SD Card be going bad, or could my Switch be?

If your games are underperforming or stuttering, this may be the problem, at least it was for me.
I'd recommend doing a speedtest on your MicroSD using https://github.com/JonMagon/KDiskMark/releases/tag/3.1.2 just to be sure your card is genuine and performing to spec.

Weird download speed issue
But the theoretical write speeds definitely do not apply when it comes to the steam deck, you have an adequate card but I advise you do a speed test in desktop mode using https://github.com/JonMagon/KDiskMark/releases/tag/3.1.2 to double check the actual speed you're getting, it'll likely equate to no more than 80mb/s write which is most definitely not enough to handle download speeds of 70MB/s considering steam unpacks as it downloads.

New to Steam Deck (and PC as well as Steam in general). I have a multitude of questions…
Since owners of this MicroSD card are few and far between, would you mind testing its speed and performance for me, using KDiskMark? You can download the program from here: https://github.com/JonMagon/KDiskMark/releases/tag/3.1.2

PSA: A MicroSD card guide that seems to be sorely needed
Hopefully that provides an insight into why 'U3 A2 UHS-I' is the ideal card you should be looking for with the deck. I would always recommend when you purchase a new card that you run 'Kdiskmark' in desktop mode by downloading it from here: https://github.com/JonMagon/KDiskMark/releases Check the latest release and download the file ending in 'appimage'. From here open the folder it downloaded to, (don't open it from Firefox as it won't know what to do with the file) double click the file and should open the Kdiskmark window. From here you can select your MicroSD card and do a speed test to make sure you are hitting the advertised speeds!

After weeks of frustration and headaches with download speeds I found a solution
I'd recommend you download kdiskmark from here: https://github.com/JonMagon/KDiskMark/releases/tag/3.0.0 (Download the one ending in appimage as it doesn't need an install)

Why is downloading and verification so slow with my SD card?
Try testing your speeds with kdiskmark

Dire SMB speed with on PC to NAS
Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio

Ask HN: What are some good resources for learning about low level disk/file IO?
Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy.

KVM virtual machines on ZFS benchmarks
The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway.

SSD Sequential Write Slowdowns
All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied.

Just write the f*****g parser.
Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.
