  • I was and still am on HDD. The CPU was upgraded as well. I migrated to a new server.

    The main culprit was the database. As far as I’m aware Lemmy is missing some indexes and due to the ORM they used didn’t always have optimised queries. Now with 64 GB RAM the whole database (almost 30 GB) fits in there fixing most of those issues.

    The real fix will probably come with Lemmy 1.0. They radically changed the database layout and queries.

    Image proxying wasn’t bad for performance. Just storage space. It was growing really really fast. Now that only I am using it to host the pictures I uploaded it is still much too large (24 GB). But its directory structure is so convoluted that I can’t really debug it. My stuff really shouldn’t be taking up more than a few hundred MBs.

    I am the only one using this instance. I am subscribed to a hundred communities or so. I am always pretty up to date with my Lemmy versions.





  • I run an instance just for myself and it was a nightmare on HDD and 16 GB RAM. It was slow as molasses. Supposedly the database layout will be fixed with the 1.0 release that is just around the corner.

    Since I upgraded to 64 GB it’s been pretty smooth. Still wild that that is necessary for a single user.

    Also, disable image proxying. I have no idea what pict-rs does but it seems to be too much.

    You should consider running Piefed instead. It’s not as resource hungry as Lemmy.




  • The kernels (and accompanying modules/drivers) are more or less freely interchangeable.

    Bugs in the kernel are pretty rare in my experience. I think it’s more likely that the bug was somewhere in KDE Plasma. Kubuntu’s version should be older than the one on Cachy. On top of that Kubuntu has their own patches for KDE, so even if the version numbers are the same they are not the exact same programs. And on top of that the way they compiled KDE will be slightly different.


  • That’s the way it goes with the scale from simple to “something that fits our needs”. Either something is too simple or it is so complex that you can’t let your more challenged users at it. So you end up rolling your own solution.

    That’s how many companies end up with monstrous Excel or Access applications.

    The upside of having your own app that uses common open source components is that integration with other tools is easier later down the line. Make it web based and it can run on basically every computer on the planet. Use PostgreSQL or MySQL in the backend and you can easily add other frontends if needed.










  • Nvidia is the problematic one. But in most cases that just means that you have to install extra drivers after installation. In most distributions that just means installing an extra package and rebooting. Don’t go to the nvidia website for that.

    If you are already familiar with a Linux distribution use that. If you have a friend who uses Linux use the same thing they do. Or just use Mint.

    You can change the way your system looks and works by choosing a different desktop environment. Many distributions just have one default but you can always change that later on. The big ones are Gnome which is a bit more like Mac OSX and KDE which is more Windows like. KDE also offers much more customisability.
