My network problem (the high latency) was fixed by the ISP (at least for
now), but I have tested the updated recursor with a latency simulator
The results are:
Works great for all sites I tested with up to 5600ms latency (provided I
set the 'network-timeout' to 6000).
I did not test beyond 5600ms of latency; I do not see much point, as
networks with that kind of latency are almost unusable anyway.
Having it auto-tuning would be nice, as that would save the problem of
needing to manually change it in a network event.
Thank you for the patch!
