Description
From Michael Simacek on javadoc-dev:

I thought about improving performance of the default doclet implementation a bit.
According to profiler results, most of the CPU time is spent in constructing the member map in VisibleMemberMap.java.
So I've rewritten part of the VisbleMemberMap and reduced the javadoc run time to 60-70% of original run time (on large inputs).
