can't say yet, everything (entry, nostr relay, exit) is running on the same remote host right now. I've managed to scp with 2 MB/s, but that really doesn't mean much.
# an easier way
export NPUB1="$(ip_address_from_nostr mynpub)"
ssh $NPUB1
I notice you're still using id_rsa to log in. Signing in with a nostr key would be very nice.
