What transfer speed do you get doing an FTP transfer across the link?
10base is theoretically capable of one meg per second, and experience
indicates that a 10baseT link normally shows just under 500k per
second flat out, presumably due to the half duplex nature of the
10baseT protocol. I'd expect 10base2 half duplex to be similar, and
10base2 full duplex to be somewhat faster.

One slight problem - 10baseT uses CoAxial cable, not RJ45 - and, as
far as I'm aware, 10baseT is strictly half duplex whereas 10base2
(which uses RJ45 twisted pair cable) is capable of either half or full
duplex.

I have to admit that doesn't surprise me.

I can't help there, sorry.
Best wishes from Riley.
