[phenixbb] advice for speeding up cif_as_mtz

I'm currently running cif_as_mtz and model_vs_data on the whole PDB as part of my dissertation. Time has become a critical concern, and cif_as_mtz (dev-1141) is running very, very slowly (1-4 minutes per entry). Here's how I'm calling it: phenix.cif_as_mtz --ignore-bad-sigmas --merge --remove-systematic-absences --map-to-asu --symmetry= --output-file-name= I'm hoping that perhaps someone could help me determine which command line argument(s) could be removed to provide maximum speed-up. Thanks. :) Eric
