Of the order of a hundred megabytes a second is indeed what you might get
with various crypto operations on a modernish processor (which of course
do have some instructions that help).

But to be sure you need to find out what algorithm is used beyond key
exchange.

You can then run something like "openssl speed".

Then consider whether this really needs securing and if so could you use a
lighter algorithm. I assume you don't really have a need to transfer data
securely across processes on the same machine. That would be silly and
better done using common OS security  (if only nodes could connect via
UNIX domain sockets). Otherwise you still have Gigabit ethernet speed. So
what is the problem again ?
