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.
