So I’ve successfully unlocked the full linux functionality in my Atrix 2 webtop following this tutorial, and replaced the stock Motorola application launcher with XFCE4. This webtop is really nice: a full Ubuntu distribution for ARM that uses the Android kernel, so you are not emulating or virtualizing anything, the system runs directly on your phone’s hardware. But aside from my not-so-objective opinion while using the webtop, how’s the real performance? So I prepared this simple command line benchmark.
The benchmark is really simple:
trantor:~ ngranek$ time echo "scale=5000; a(1)*4" | bc -l > /dev/null
This uses the UNIX bc utility to perform a really long calculation. I don’t want to benchmark the storage (SD cards are slow, we all know that), so this simple command will do.
On my MacBook Pro mid 2011 (i7, 8GB RAM) the output is:
trantor:~ ngranek$ time echo "scale=5000; a(1)*4" | bc -l > /dev/null real 0m24.667s user 0m24.663s sys 0m0.005s trantor:~ ngranek$
25 seconds, not too bad. On the other hand, on the Atrix 2 (1Ghz dual core TI OMAP 4430, 1GB RAM):
adas@localhost:~$ time echo "scale=5000; a(1)*4" | bc -l > /dev/null real 2m22.241s user 2m19.078s sys 0m0.063s adas@localhost:~$
2:22 mins, not too bad at all. Here are the screenshots for the benchmarks, and a bonus one for my son’s Canaimita (1.6 dual core Atom CPU, 1GB RAM):
