Normally NICs auto-configure to their potential; it would help if you
showed us your configuration:

Which utilities? Also, are you sure they are reporting 80 Mbps, and not
80 MBps? The difference is a huge factor (eight (8)) so that matters a
bit. Using the former, you’re slow, but using the latter you are closer
to the maximum theoretical speed than not.

There is no such thing as a gigabit hub, so yes those are either switches
or else they are nothing.

That depends on what you are doing. Just because two utilities claim
their maximum is 80 MB/s (or Mb/s even on the slow end) does not mean that
they are measuring the potential. If they use disks to write data
(foolishly), that means disks could slow you down. If they use
encryption, that could slow things down. If they use plain old TCP
sockets, but they somehow limit the MTU to something smaller than the
maximum allowed by hardware, that could slow you down. If your switches
or other hardware are not optimized, that too. If you are going over too
many hops (switch, then router, then another switch), any of those, or the
combination of them, could slow you down.
