[Clusterusers] long running renders

[Bassam Kurdali]

We can hold off changing anything for now - I really feel something has
to be wrong with the files to get such long rendertimes, but I don't
have experience with maxwell. I'd never use it if that was 'normal'.
I'm going to try to get some free nodes from renderstreet - I just
emailed them (they typically offer free rendering to open movie
projects) and perhaps I'll try quarnot as well though I don't have a
relationship with the latter. If it works out we won't need to use the
farm as much - I'm trying a render on it right now and it doesn't seem
too too terrible; we're getting about 45 mins to an hour per frame on
this particular file at about 14 nodes concurrent. At this rate our
shot should finish in 4 days, I would probably have expected a day or
less in the old days, but it is hard to compare since it has been a
while.
I'm probably going to pause this particular render - based on the
settings, it looks like it is optimized for gpu- and prioritize another
shot from another artist. He's going to do preview quality render, so
I'm hoping we can get a turnaround of a day, if that works out it is
acceptable. 
cheers
