Title: perf($parse) Use a faster path when the number of path parts is low

perf($parse) Use a faster path when the number of path parts is low

Use a faster path when the number of path tokens is low (ie the common case).
This results in a better than 19x improvement in the time spent in $parse and
produces output that is about the same speed in chrome and substantially faster
in firefox.
