Raspberry Pi Crude Benchmark

I created a very crude calculation benchmark to compare Raspberry-Pi against Alix and MicroClient Jr, calculating PI to 2000 decimal places:

time echo "scale=2000;4*a(1)" | bc -l

Here are the results:

Raspberry-Pi : 0m25.210s
Alix: 0m42.063s
MicroClient Jr: 1m32.134s
