How long does it take to sync a new cardano-node server running v1.29?

1.29.0 actually introduced a memory usage increase.

There are a few related topics on the forum. Try looking them up:
ie:

Upgraded to 1.29.0 - High memory usage

I did not see an increase in RAM usage from 1.27 to 1.29. Still running without missed slots with 8GB.

Solving the Cardano node huge memory usage - done

After months of research, worry and despair I’ve finally solved my relays and producer memory usage problem where some of my relays would end up using all of their RAM and start swapping and suffering from IO delays until restarted… I’ve hesitated a long time before making this post because why in the hell would I share a competitive advantage like this one? Since all SPOs are competing against each other, in a very harsh environment where the rich still have a very unfair advantage over hard w…

1.29.0 is by default configured to use 2 CPUs. There are ways to configure it to use more CPUs with the RTS and -N flags. I think the bottleneck is the processing power while syncing. IIRC using htop you should see some cores running 100%.

Usually when RAM becomes the problem the process will be killed because OOM, which you can observe in the logs.

My nodes run at about 8.2GB RAM usage currently.
