    Description

      For high-bandwidth Ethernet interfaces (e.g. 100GigE), it would be useful to create multiple TCP connections per interface for bulk transfers in order to maximize performance (i.e. conns_per_peer=4 for socklnd in addition to o2iblnd). We already have three separate TCP connections per LND - read, write, and small message.

      For large clusters this may be problematic because of the number of TCP connections to a server, but for smaller configurations this could be very useful.
