Please describe the feature you'd like to see added.

As a user, I want Bitcoin Core to utilize maximum resources (CPU, network bandwith, memory) so that intensive operations are perfomed faster (take shorter time), e.g. rescan after importing a key to a wallet opened in a pruned node.

Is your feature related to a problem, if so please describe it.

There is the problem that intensive operations take long while computer resources are not utilized in full:

• CPU utilization never exceeds 30%,
• bandwith utilization rarely exceed a few MB (approx. 10-20% of capacity, wired),
• RAM < 50%,
• disk (SSD) rarely exceeds a few %.
