I'm totally sure the RSA operations are using the AES instructions

generating (fresh) rsa keys? you don't do that on connection to a SSH server
as for what actually happens on connect, 2004 laptop: 33 signatures/second and 2200 verifications/second (+DH/ECDH)
the RSA operation (verifying the server's host key) took a total of 0.0005s
even my raspberry pi 1 can do 240 4096-bit verifications/s and several thousand ECDH's/second
and I have yet to see a SSH server with 4096-bit host keys
tldr: even old computers are fast (and data > supposition)

- blibble 5y agoI did exactly what you told me to I suggest reading up on how the SSH protocol works
- kalleboo 5y agoThere are people in this thread with actual experience and actual bench times using these protocols on machines of that period https://news.ycombinator.com/item?id=28022299 https://news.ycombinator.com/item?id=28022299 https://news.ycombinator.com/item?id=28023337 https://news.ycombinator.com/item?id=28023337

- retrac 5y agoPerformance increase did not stop; smaller, better designs. The exponential is just a bit lower. We don't realize it, just as someone using a text terminal may have not realised it between 1985 and 1995, if every response after a key press was already instant. For typical GUI interfaces, tasks like tossing video data around, and so on, computers became approximately inifinitely fast sometime c. 2005 - 2010.
- anthk 5y agoEh, no. Windows' 10 UI latency it's abhorrent. If any, current gens with Electron crap are doing it far worse. Far, far worse.
- anthk 5y agoYour damn 2004 laptop could emulate the Amiga and the Mac with a 68k CPU in parallel. The Rpi? For FFS, an Rpi B+, a PSP, or a 2003 Athlon XP could emulate a System7 era Mac with a Quadra setup without a single slowdown.
