Technically, it's faster. Mounting it doesn't need to do any journal
shimmying, so it saves a few milliseconds. It's actually the same
rationale for using a separate /boot - it's faster to mount a 100 MB
partition than it is to mount a 120GB partition/disk.

All-in-all though, these doesn't make a significant difference as
boot-time bottlenecks happen at other places. I will point out though,
that on my "omg fast boot" mythtv machine (which is now the arch64
build machine), I was able to save 2 seconds on boot by doing these
tricks - I actually got it to boot to console login in 7 seconds. It
was fun.
