Hi,
We've got a C function that we use here and we find that for every
connection, the first run of the function is much slower than any
subsequent runs.  ( 50ms compared to 8ms)

Besides using connection pooling, are there any options to improve
performance?

In my experience, connection startup takes a heck of a lot longer than
50ms, so why are you worrying about 50ms for the first run of a
function?

BTW, sorry, but I don't know a way to speed this up, either.

I think Tom nailed the solution already in a nearby reply -- see preload_libraries on this page:
