Current Behavior

Hello.

I'm trying to POC migrating from ethers to viem in our code base. Loving viem so far but experiencing a significant degradation in typescript's performance. Especially when using extend and even more so if inferring multiple chains when creating the client.

I saw a closed issue that was opened in May on the matter. (#2322)
Is there anything I can try to improve the performance?

Expected Behavior

Blazingly fast type inference :D

Steps To Reproduce

create a client with a union of networks and extend it. Then see that every completion takes 1-2s
