Did that change? I’m still using 4GB but I haven’t done an initial download for a couple years now.

I have a node running on a thinkpad. Switched to 8G of RAM & everything runs a lot faster.
Might not be the issue, but you could try & see if it works
I run it on my daily driver, which has 32gb of memory and NVMe. Takes about 8 hours. Most of the time is literally writing the transactions into the database, because usually there's a checkpoint less than a year back so the majority of it only needs a check of the sequence of block headers and then writing the transactions.
