Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Lemmy resembles the old reddit experience so well that they even emulate the old reddit server performance (lemmy.world)

The "all" stream would be all of the posts from the combined subs of the users on the instance. So if there's a community nobody is subscribed to, it won't appear on all. This is true of all instances. Many smaller ones will employ bots to crawl Lemmy and sub to communities to give the large instance "all" feeling.

That being said, yeah it's all preloaded onto your local server. There is no difference in speed. Doesn't matter if it's active/subed or new/all they all load the same

I'd highly encourage everyone to find smaller instances and leave lemmy.world for the immediate expats. Find something that aligns with your values. Or if you are technically literate enough host your own instance. If you have an old desktop computer you've already got everything you need.

I should probably build an instance on my little home server. Is there a guide for that somewhere?

Right on the lemmy website. 🙂

It can apparently take up a decent amount of space depending on how many communities you subscribe to.

I do that on my own instance too :D, private and small instances are really the way to go!

How many communities you subscribed and after two weeks how much data does it represents on your storage ?

[–] [email protected] 4 points 1 year ago

Not OP but I can answer with my own stats:

In just a week, With BTRFS compression (compress-force=zstd:3) & deduplication (via bees), media is at about 1GB (and I am subscribed to media-heavy communities like 196) and the postgres DB is at about 550MB (which is also currently shared with Matrix Dendrite)

At "idle" (as you can be while being connected to ActivityPub & Matrix), the immediate CPU and RAM usage breakdown per container is:

NAME        CPU %       MEM USAGE / LIMIT  MEM %       NET IO             BLOCK IO           PIDS        CPU TIME         AVG CPU %

Net IO you shouldn't really care about as that includes inter-container networking. I'm trying to find how much outgoing data have been transferred but because the month just ended I have no idea how accurate the numbers are.

On my instance we've got about 100 communities subscribed to. Started it first week of June, since then the instance is up to a little over 4 GB of disk space. YMMV depending on instance size.
