Rational
========
1. OpenWrt is the most popular distro for WiFi routers; many of its
targets use big endianness [1].
2. 4 out of the top 5 bestselling WiFi routers in the US use MIPS [2];
MIPS uses software-managed TLB.
3. Memcached is the best available memory benchmark on OpenWrt;
admittedly such a use case is very limited in the real world.
