This was run on revenue: (opening an X display on my Fuel workstation)
bin/manta -np 8 -imagedisplay null -bench -camera "pinhole( -eye 852.55
-380.453 114.667 -lookat 1044.98 -383.53 113.746 -up 0.110811 0.157369
0.981303 -fov 60 )" -scene "lib/libscene_boeing777.so( -file
/dev/shm/engine.v3c1 -np 8 -alpha 1.0)"
Why the need to set the FGL_MACRO_TILE_FB env variable? It doesn't seem to
affect my results (after trying it once).

Please send me the command line and the hostname. I will investigate.

I ran the following two commands on fisher and only saw a 9% difference:

Also be sure to "setenv FGL_MACRO_TILE_FB 1" in your environment.
