> Computing fingerprint can very costly and take time. But the current 
> implementation will send requests for getting fingerprint for multiple 
> replicas, then on the first response it will then compute its own fingerprint 
> for comparison. A very simple but effective improvement here is compute its 
> own fingerprint right after send requests to other replicas.
