Typing lag...that reminds me of something I saw in the 90's. Someone was trying to figure out a production problem and asked for help. I sat down at their computer, and was trying to use their terminal shell window (HP/UX). It was terribly laggy, worse than I'd ever seen before. I asked if it was OK to exit and open a new window and they said OK. So I typed exit to close the telnet connection, then exit again to exit the terminal...but it didn't go away. So I typed exit again. and got another shell prompt. At that point I realized that they had been hopping from machine to machine without exiting. It turned out that the lag was from 22 nested telnet commands!
