> Your laptop from 2014 was already running at LEAST a 64bit CPU and likely has AES instructions as they were introduced in 2010 [3]

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)

Your 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.

TLDR: You're not using era appropriate examples.

I told you to get off my lawn.

I did exactly what you told me to

I suggest reading up on how the SSH protocol works

There are people in this thread with actual experience and actual bench times using these protocols on machines of that period

You must be young. The gap between 1989 and 1999 in computer terms is inmense, far more than the gap between 2010 and 2020. You could emulate a 1989 m68k Mac/Amiga on a Pentium 3 from 1999, for example with BasiliskII/UAE.

Performance 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.

Eh, no. Windows' 10 UI latency it's abhorrent.

If any, current gens with Electron crap are doing it far worse. Far, far worse.
