Every instance is like this it seems, maybe lemmy doesn't make a batched select at the cache and the db, but idk.
Maybe a new ~~webscale~~ backend could solve this, but i'm just a java backend developer, not a rust one. Maybe could be an interesting project, scala + pulsar + batching, turning lemmy into a microservices hellscape.
Edit: but
Searxng with brave, duckduckgo, google, mullvadleta, mullvadleta brave and qwant as the search engines. Law of big numbers makes it quite useful.
