That is indeed an interesting paper.

Just to be a bit pedantic, their measurement of syscall latency showed
that 32-bit apps on a 64-bit kernel are slower than 64-bit apps on a
64-bit kernel.  But, that's not the same choice you would have when
deploying to EC2.  If you use a 32-bit instance you will have a 32-bit
kernel.  (But, it probably is still better.)
