Rsync is the fastest, I think. If you want fast scp, you can try to change cryptographic algorithm ssh/scp uses for transfer.hello,I have a buster PC and a bullseye PC which are both supposed to have gigabyte network cards connected via a little Gigabyte switch box. Transferring files between them, I forget which shows the transfer speed per file, either scp or rsync the maximum is 50 Mbs per file.Would you expect that to be quicker ? mick
In older time it was possible to force ssh (scp) to use arcfour crypto, which was able to yield about 900Mbit/s even on old CPU in a single thread with 70% CPU utilization (Dell R220).
I don't know which one is the fastest from those left after great excommunication of obsolete crypto in ssh 1:7.6p1-1.
