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.)
