bitcoin-qt slows to a crawl

My saga to get a full node working once more continues: I began over with a contemporary set up of 29.0 and eliminated my datadir utterly.
Initially it seemed good, and I made good progress synchronizing, however as I get to lower than two 12 months behind, there’s hardly any progress.
I embody the debug log from my bitcoin-qt -datadir=/u/bigdata2/,bitcoin on my Ubuntu 22.04. In the direction of the top you may see simply how lengthy it takes to advance only one block.
Any assistance on find out how to debug this ituation can be extremely appreciated.
Cheers,
Merlin
