idea.exe.vmoptions being ignored?

I modified idea.exe.vmoptions to say:

-Xms128m
-Xmx800m
-XX:MaxPermSize=400m
-ea

Yet the max memory displayed in the bottom corner when Idea is running is 250M.  What gives?  Where does that number come from?

It is taking forever to update the project indices, far longer than in the old version.

If I am not mistaken, I think the JVM releases memory in chunks does it not? As an experiment try setting the -Xms argument to 800 as well And you will not you will have on startup around that much memory allocated. I usually set my memory the lower and upper levels to be the exact same.
