The party line is that if the node hasn't satiated its
connections (the limit specified in gnunet.conf), it will
aggressively try to establish new connections. The
connection table is impossible to fill if the limit
is 64 (as default) and yet there's only 10 or so nodes
online concurrently. And if there's no other traffic,
the node will still forward HELOs frequently, perhaps
it'll change session keys too (not sure), but always
the difference between the content size and MTU will be
padded with noise, or if enough space is left, with
low-priority data.

There might be much tuning to do, but still the overhead
should be minor compared to traffic it can take/generate
when operating in a busy network at full blast. ;)
