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](https://forum.cardano.org/t/upgraded-to-1-29-0-high-memory-usage/70688/38):

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

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.
