You can’t compare older and newer nodes like this. New files are more likely to be deleted and incomplete transfers can lead to trash after garbage collection. Since all data is new and recently transfered on a new node, higher percentages of trash are to be expected.
@luckins, I don’t think it’s anything to worry about, but it might be useful to have a look at your transfer success rates by using the script here: Success rate script - Now updated for new delete terminology since v1.29.3
Post your results here so we can have a look if anything is off.
Just to get ahead of some questions that might pop up. How is your node connected to the internet? Are you using a VPN? How is your node connected to the storage? SATA/USB/SMB/NFS/iSCSI?
