Very slow network reads on ARMx6 with LanMan98

I used a 1000Mb/s USB adapter on my laptop when the ARMX6 correctly negotiated 1000Mb/s full duplex. When plugged directly into my laptop the ARMX6 correctly negotiated 100Mb/s full duplex so ethinfo is correct. You can read the registers on the ARMX6 ethernet chip directly and everything seems ok.

Slow transfers usually come with the hourglass appearing so something hasn’t happened for at least half a second – implying that it’s waiting for a response which has been dropped which makes flow control a suspect. Love to know what risc os is doing when it’s showing the hourglass. This isn’t a problem peculiar to an ARMX6 or Lanman, ShareFS can hourglass a lot if you connect a slow machine to a fast one, sharefswindow alleviates the problem by slowing down the fast computers.

Ah, that wasn’t apparent from what I’d read, re-reading I see what you mean.

If it’s really flow control then EtherK has
*Configure EKFlowControl None | Generate | Respond | Full

Although, connecting running wireshark on the PC end and then examining the conversational flow is probably going to be required.
