The lock()/unlock() is a likely contributing factor, and having such a
large number of blocks is
  likely to exacerbate any underlying deficiencies in that area.

That's a lot of blocks, which means that there's going to be a lot of
data shuffling going on inside
  the block scheduler.  Try to merge blocks if you can.  For example,
adjacent multiplies can
  be merged into a single multiply, etc, etc.   With that many blocks,
you'll be chewing up
  MFLOPS pretty quickly.
