No.
RSA or other asymmetric crypto is only used during connection establishment for authentication. Then symmetric key is established using DH and you use symmetric encryption to encrypt the data.
- nickysielicki 10y agoThat makes perfect sense. Apologies for spreading incorrect information, and thanks for correcting me. I remember changing around my ssh config a while back and seeing lower speeds when rsync'ing from an older laptop. But that makes sense, I recall cranking up my DH group to 16, 4096-bit, and that was probably why it was struggling.
