High latency setting optimization

We are running multiple unbound caches behind very long latency 
sat links. We are seeing RTT of at least 1000ms. 

Sometimes recursing times spike up to 20 Seconds.

Is there an optimization guide on how to fine tune parameters
for those situations?

I have already seen jostle-timeout. I am pretty shure prefetching
has a huge impact.

Anything else?
