A few questions: * How did you obtain the ParaView executable? (download, build)? If you built ParaView in Debug mode, that could slow things down.
* How big are your data files, both in terms of disk size and grid elements? * How much RAM is on your system? - Cory On Wed, Oct 21, 2015 at 8:50 PM, Andy Bauer <[email protected]> wrote: > Did you profile this at all to see where most of the time being spent? > > Looking at this, I don't see anything really bad.
