Repro Steps

curl --silent -X POST -H "Content-Type: application/json" \
             --data '{"jsonrpc":"2.0","id":2,"method":"Filecoin.StateGetBeaconEntry","params": [ 1 ] }' \
             "http://127.0.0.1:1234/rpc/v1"

First run takes well over a minute (91s on my machine)

Describe the Bug

It is a regression from old performance (pre https://github.com/filecoin-project/lotus/issues/12414 and pre change that lead to creation of this issue), where it took significantly less time to get that beacon information (the results are identical).
