Hi,

  We have the following system and have found that Coot (0.5.2 and 0.6) runs
very slowly:

-Dual Xeons @ 3 GHz
-4 GB RAM
-nVidia 256 MB Quadro FX 3450/4000 SDI
- >250 GB hard drive space
-Red Hat Enterprise Linux WS release 4 (Nahant Update 7)

Rotating a 500 amino acid model is fine but when we open map (.mtz) with it
the rotation drags as does walking along the chain.  Increasing the Map
Radius makes it worse, decreasing it makes it better.

We have another system that is less powerful but runs smooth using the same
model/map.

Where should we start troubleshooting this?

Thanks,
Jon
