Might I point out that discussion is with respect to an 8k RSA SSH key
for SSH authentication, not for email. A 2 second delay during the
initialization of an SSH connection is not a problem.

Find one with a better battery/more-efficient processor if these sorts
of calculations would really be an issue, compared to the general
radio use of the phone.
