Somebody asked me about ARCNET performance problems with mTCP, and I went down the rabbit hole. They are using the ARCETHER packet driver as mTCP is only designed for Ethernet. With smaller packet sizes it works fine but the performance is bad. With larger packet sizes and buffers it runs into flow control problems and the performance really suffers.
I might want to debug this myself, but I know I'd need to find ARCNET cards. I know that for just wo machines a single cable will work, but the cable is supposed to have 93 Ohms of resistance which seems unusual and non-standard. (I have to get RG62-U, but it looks to be readily available.) For more than two machines I need to find an active or passive hub. Is there anything else I need to know?
