You made a claim (which has no link to the other thread) which is
questioned by Julian and I would like to have numbers which may support
your claim. That's all.

If you don't have numbers, don't claim performance gains....

Because the your code using the map does not care. It is just one single
location which cares: the point where you create the object. So if your
code just uses a map, why declare it a HashMap -- you might later decide
to use a GrokMap or a StupidMap instead of HashMap and you don't want to
change your code except for the constructor, do you ?

(And yes, this is also different from the main discussion thread)
