FYI:
phenix.fmodel rarely takes more than 3-5 seconds to run. Under the hood it is simply iotbx.pdb.input to fast-process PDB file, and then Fcalc from xray_structure. If bulk-solvent contribution is requested then the time for mask calculation (which is fast too) adds to the total runtime.

Here is another one:

iotbx.pdb.as_xray_structure model.pdb --fake=2.5

Faster than phenix.fmodel, but no bulk-solvent correction.
