Actually I wasn't clear in my original post, I didn't really mean so
much that the DST was slow itself, but rather that it simply is taking
too long for my application, which requires many many streamlines to be
generated. My first tendency is to throw more processes at it in hopes
of a speed up. but in reality that really hurts the DST performance.

When you say slow, can you quantify that? Also, what is the size of the mesh
in the regions where you are generating the streamtraces? I ask purely
because I've always found streamtraces to take a long time regardless of the
application used.

Subject: [Paraview] distributed stream tracer scalability issue
We've been using the distributed stream tracer to generate 100s-1000s of
stream lines per time step. It's very slow, and it doesn't scale at all.
The class comments say as much. I'm sure there is a reason why this
implementation was chosen. Is there something that generally prevents real
parallel implementation? Is there a better implementation available out
there?
There is this post a while back

What's the status?
Thanks
