Hey all, don’t get too excited. A 2GB Lemmy instance has very little data going through it. My instance, which is just me, and auto-subscribes to communities with “Top” posts using LCS, processes about 10GB of new data a day.
Without subscriptions, the Top, Hot, etc feeds would basically be empty. So if you only want communities you subscribe to, IO will be low, but if you want a full experience, disk and IO will be your bottleneck.
All that being said, thanks to OP for giving the community all this extremely helpful info.
