WorldState resync takes too long on some good setups

[ahamlat]

Description

Some users reported very slow resync time on the world state when using this curl command :

curl -X POST --data '{"jsonrpc":"2.0","method":"debug_setHead","params":["0x1211F34"],"id":1}' http://localhost:8545

Example
On a 2 TB A-Data XPG SX8200 Pro, it took 15.5 hours, with Besu running on Docker.

Expected behavior: [What you expect to happen]
WorldState resync should take predictable time regarding the used hardware.

Actual behavior: [What actually happens]
Sometimes worldstate resync takes too long even on good setups

Frequency: [What percentage of the time does it occur?]
Hard to say, we've seen some users reporting this behaviour recently.
