Are you sure?  
I disabled Tor by commenting out the 3 lines in bitcoin.conf:

# Tor

#proxy=10.21.21.11:9050  
#listen=1  
#bind=10.21.21.8

and it seems to have a big impact on sync speed (X2 network bandwidth used, and more than 10 blocks received per second).

I’ll monitor to see if the speed slow down with time…

I confirm. Blockchain sync is way faster with tor deactivated.  
Then, I reactivated it once synced, and it works fine.

Just built an Umbrel node on Debian and the command @DarthCoin gave didn’t seem to work. Gave multiple trace back errors. Tried the command you gave and got permission denied. Threw sudo in front and bam. Flying thru these blocks. Thanks!

Yep, thanks for pointing out, that command was wrong. I correct it.
