ColdFire Network Benchmark

Blunk's Network Benchmark Test transfers 10,000,000 bytes of data over TCP between a target board and a PC that are connected via a 100 Mbps switch. The target board runs first a chargen client and then a discard client, communicating with Windows XP servers on the PC.

We measure the throughput and percent CPU utilization. The following results are for Blunk's TargetOS/TargetTCP on the M5282LITE and M5474LITE boards. The compiler is GCC.
