- Contrary to what the hi-po graphic$ work$tation people will tell you,
- a PC with carefully written drivers will perform very nicely. For
- example, if you purchase a copy of QNX 4.1 (shameless FLEET plug) and
- a couple of inexpensive NE2000 (novell) compatible 16-bit ethernet
- network cards, you can measure a user space-to-user space (guaranteed
- non-duplicate delivery) unidirectional data transfer in excess of one
- million bytes per second continuously between two 486/33 PCs.
-
- Not bad, given the cost of the network hardware - I've heard rumours
- of the street price for the NE2000 clones dropping to $75. I prefer
- the novell (clones) to the wd/smc 8003 series, mainly because the novell
- uses no shared memory, and the 8013 can be a pain to wedge in. Also,
- I've observed that the NE2000 clone cards are about 7% faster than the
- 8013. Cheaper too.
-
- In my experience, 8-bit ethernet cards will hurt your performance
- noticeably, even with decent drivers. You will see in the neighborhood
- of 600K +/- 50K bytes/sec, depending on the whose card you are using.
-
- Interestingly enough, I've observed almost exactly that same speed
- (570K/sec) on an 8-bit ISA 16Mbit IBM token ring card, on a two-node
- network.
