Odroid-U2 is fast!

Odroid-U2 is really fast. I built Seamonkey 2.22.1 (the latest at the time of writing) on it - it took me only 2 hours 45 minutes. This compares favourably with building on my 64-bit x86_64 laptop which is about 2 hours 15 minutes (or so).

It is a far cry with my original build of Seamonkey 2.19 on Mele (A10, Cortex A8, single-core, 512MB) - which took between 15 to 18 hours depending on my luck.

During the build, all the four cores of Odroid-U2 was maxed out at 100%, yet the temperature never climbed higher than 70 degrees. Odroid-U2 uses a fanless heatsink, and this heatsink - while noticeably warm - was still touchable. This contrasts with my x86_64 laptop, whose temperature climbs to a worryingly 95 degrees with its fan is being overworked to prevent thermal shutdown.

I need to revise my opinion that ARM is still playing catch-up with Intel - it no longer is. In fact, there is no Intel offerings which is on similar power/performance/price as this one. Intel Minnowboard is a single-core hyper-threaded (=dual-thread) 1GHz CPU and 1GB RAM priced at $199. Intel Galilo is a measly 400MHz single-core CPU poised to compete with Arduino. None of them are even close in terms of price/performance to Odroid-U2 (I didn't check the specs on their power consumptions) - this board and its Exynos4412 Prime CPU is in a class of its own.
