I kind of want to self host a lemmy instance. What are the requirements for a single user lemmy instance?
You must log in or register to comment.
Depends on how many communities do you subscribe too and how much activity they have.
I’m running my single user instance subscribed to 20 communities on a 2c/4g vps who also hosts my matrix server and a bunch of other stuff and right now I mostly see peaks from 5/10% of CPU and RAM at 1.5GB
I have been running for 15months and the docker volumes total 1.2GBs A single pg_dump for the lemmy database in plain text is 450M
For the whole stack in the past 16 hours
I subscribe to a few more communities and my DB dump is about 3GB plain text, but same story, box sits at 5-15% most of the time.
Thanks.
Put up some docker stats in a reply in case you missed it on the refresh
Checked it out, thanks.
These stats are fine and all, but storage and network is what’s going to get you in the end if you open it up to anyone and everyone and it becomes popular.
I have one running on the equivalent of a pi. It works no problem. The biggest issue is the constant io and network traffic but it’s not terrible.
I wish there was a only poll once every x amount of time instead of the constant polling, but it’s a good solution. I use lemmy.world as the main account and the other account when I need to post under my real name with some projects I run. Plus it makes for a good development instance since I work on lemmy from time to time
I did this for a while. However, after subscribing to several groups, there was constant disk activity and it ate network bandwidth. After two months I’ve stopped my server and went back to using a public instance.
Sure. It’s constantly pulling all the posts, comments and likes from potentially hundreds of instances and writing it to it’s database to make it accessible to you once you decide to open Lemmy. It’ll get updates from the network every few seconds (unless all the Americans are asleep) and that’ll cause some database operations on your side.
Concerning the requirements: You’ll need some form of server, and probably a domain name. If you’re doing it at home, make sure you have a proper IP address and can forward ports. I run a Piefed instance, not Lemmy. It uses a few hundreds of megabytes of RAM and a bit of CPU and disk. It doesn’t cache media files as Lemmy does so I can’t comment on the storage size. It’s 3GB for me.
Thanks.
How intensive was it exactly?
I didn’t notice any big drops in network or CPU performance. Usually, because other network traffic had priority. But my server’s HDD constantly rattling along got me thinking that it wasn’t worth it. There are several other containers running on that box and I don’t have that much HDD activity with them.
There are postgres settings to reduce disk writes. There’s a max size and a timeout to write to disk. By default these values are on the lower end I believe.
Yeah, but I didn’t want to fiddle with some custom settings. The same official postgres container works great with other apps.
Yeah works good until its under load which federation does have. Matrix and Lemmy both got like 20GB of RAM dedicated to the database on my servers.
Thanks.
