README for the programm speed.c


This is a small program to test the data-transfer rate of your link interface.
It assumes that your link-device is named /dev/link0.
When you start the program it sends a file named speed.b4 to your root-transputer
and then tests the data-transfer rate reading 100 kbytes from and writing 100
kbytes to your root transputer. All time measurements are done by the
transputer's timer channel.
The occam program was compiled with the TDS, the c-program with gcc 2.4.5 and
libc 4.4.4.

Compiling the c-program on a DOS-box will allow you to compare the link speed
using DOS and linux. On my machine I have the following data-transfer rates,
measured under linux 0.99pl13 and DOS 5.0:

Linux:
	reading: 390 KBytes/sec
	writing: 450 KBytes/sec

DOS:
	reading: 205 KBytes/sec
	writing: 209 KBytes/sec
