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. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

Question about this, is it just a speedier general browsing on other instances as well? Or just your local posts?
Everything is faster. For the most part, your local instance will download posts and comments for any community you (or anyone else on your instance) is subscribed to. So when you log in, you log into your server and browse the content locally (posts from everywhere) while your server in the background constantly is receiving updates through the ActivityPub protocol.
I literally have no delay in using Lemmy in any way.
What about the "all" stream? Is that also preloaded to the server?
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. ๐

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

There you go, enjoy
How many communities you subscribed and after two weeks how much data does it represents on your storage ?
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:
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.
I do that on my own instance too :D, private and small instances are really the way to go!
