As someone else pointed out, one of the reasons for IL was to have something
useful before we had a reasonable TCP floating around. TCP is considerably
more code even before you start adding congestion control. It made getting
a number of small special purpose systems up and running quicker to use
someting
like IL. I couldn't have imagined getting TCP into early versions of Ken's
file server.
However, now that we have a mature TCP, I don't see a lot of reason for IL.
When we provile the code for both IL and TCP, the bulk of the time is still
in checksum and memmove and handling the interrupt. Most of the code in
TCP doesn't fire very often.
