=== Begin facspeed.py ===
#!/usr/bin/env python
import time
def factorial(n):
result = 1
while n > 1:
result *= n
n -= 1
return result
n = 100000
start_time = time.time()
factorial(n)
time_diff = time.time() - start_time
print '%d! computed in %.3fs' % (n, time_diff)
=== End facspeed.py ===
System SoC/CPU OS + arch time
XO-1.75 Armada 610 @ 0.8GHz Debian armel 199.108s
XO-1.5 VIA C7-M @ 1GHz Debian i386 199.285s
OpenRD 88F6281 @ 1.2GHz Debian armel 181.277s
Desktop PC Athlon BE-2300 @ 1.9GHz Debian amd64 34.180s
I must admit I'm surprised by the result. sup (my MUA of choice) feels
much slower on XO-1.75 than on XO-1.5 - and that's even though dstat
reports higher SD card write throughput (with a different card). Maybe I
should do some side-by-side comparisons.
