I am not sure if I understand the question entirely. Are you talking about
the latency of IPsec in general, or the difference between PSK and RSA?

It all depends on the hardware. IKE is not causing much latency at all,
because it happens once per hour. And if you wish to get a better
throughput for ESP, then adding CPU power or hardware accelerators will
help you.
