Really slow for lots of calls

[tuloski]

There is something in the code really slowing down for a high number of calls when using .call() with ethers provider (I don't know with web3 if it's different).
And I'm not talking about waiting the node to return the request, just calling the function is taking lots of time. I didn't look in the code very much but probably it's doing some other async request? Because it cannot be only CPU time to be that slow.
