In the common case, probably not, since sshd re-execs itself on each
connection (using a lot of code originally for -i) to provide randomization
of the runtime environment (ASLR and such). Protocol 1 connections will
need to generate an ephemeral server key so they'll probably be noticeably
slower.

usually comes from bad judgement.
