From what I was told. If you self host for only yourself, there is no benefit and you are not talking the load off anyone else’s instances. I believe because you still need to pull all that data so no difference. But if you have a few people on your instance then that will help The more you have.
I recently setup one up and it wasn’t difficult.
Biggest issue for me was user error where I didn’t think about needing an smtp service to send emails. So just got a free one that allows 300/day
