Hello,
we are using the same benchmark scripts through pvbatch/pvpython as we were in 
4.x, however with larger models we are getting odd results.  When running a 336 
million triangle isosurface of the LLNL Richmtmeyer meshkov dataset in a for 
loop that consists of:
for i in range(0,numRuns):
        Render()

We get reported render times of 30 seconds through pvbatch/pvpython.  Using 
outputs in polydatamapper, I can see it’s triggering the polydatamapper on each 
call to Render and the timing is consistent with what you might see if LOD is 
changing for each of those calls.  We set the LODThreshold to be large enough 
to never be triggered but something appears to be ejecting the polydata 
representation and regenerating on each call to Render().  If we run this 
script through the GUI using RunScript in the python shell, we do not see this 
issue, it only shows up in batch.  

Any leads on what might have changed since 4.x that would trigger this?
