Final makes no difference?

[John Demme]

I'm working on fixing and optimizing my XML parser.  It uses some classes,
and lots of virtual method calls, so I figured I could really increase my
speed by making everything final.  I made the classes final, and I put all
of the methods in a big final{} block, but it made no appreciable
difference in my time trials.

Am I doing something wrong?  Does DMD currently not optimize for final?  Or
are virtual method calls not nearly as bad as I thought? I'm making a ton
of calls into small functions, so I was also hoping final methods would be
candidates for inlining...

I'm using DMD 0.163 and compiling with -O and -inline.

Thanks
