Bitcoin Core – getbalances rpc call times out

There are Bitcoin nodes with over 800,000 addresses. Recently I faced the following problem: getbalances RPC call when timeout. I am using a timeout of 100 seconds. Increasing the timeout may work, but I’m looking for something better than this.

My questions are: getbalance "*" 1 It will take less time than getbalances? I’m more interested in receiving a confirmed balance.

Or is there another way to get my wallet balance faster than the aforementioned RPC call?
