Comment (by Hello71):
 compression pegs the CPU (of course), but consensus updates are pretty
 uncommon. malloc and free waste time I believe for every single packet
 forwarded, probably mainly because AFAICT there is no fast path that
 avoids memory allocation (or epoll waiting) in the case where the outgoing
 channel is free.
