</div>
<div>I suspect that this is a software rendering issue (Mesa). That's ~ 1.5M quads so I am still surprised that it is slow with 4 MPI ranks but I guess that's Mesa's performance on that machine. The simplest test is to use the sphere source with MPI rank and
adjust the number of triangles to get a feel for triangles/second that Mesa can handle on 1 process. That should give you a feel for how many ranks you need to handle a certain geometry size. Mesa can now be compile multi-threaded so that may be one thing
to try.</div>
