every Ethereum RPC provider seems to support batching but advise against using it

can anyone add more color here or give a use case where you think it's useful?

Building @warpcast and @farcaster / dad / like to read, cook, ski, code

We don’t advise against, we actually do it by default if you use the sdk

this is from clients? what are the advantages? what's the pseudo logic for how you batch?

Advantage is just performance afaik, full code is here: https://github.com/thirdweb-dev/js/blob/main/packages/thirdweb/src/rpc/rpc.ts

(I'd be surprised if viem didn't do this too)

Is there really a performance benefit as everyone is on HTTP/2 now?

Viem doesn’t default to it right now though. Maybe we should if there are obvious benefits.
