Have you considered that this could be a problem with TCP packet sizes and 
Nagle's algorithm? https://en.wikipedia.org/wiki/Nagle%27s_algorithm

We have identified back in 2015 that kadmin get * is slow because of
this and I don't thinks that was ever fixed because one needs to
restructure the whole send/receive program flow for this. To start
with one could use TCP_NODELAY and see if that fixes the problem.

Then if TCP_NODELAY is a permanent fix and should go into the
production code is another question (which was never solved for the
kadmin case if I recall corectly).

This was just a guess,
Harald.
