It seems that the location of Phenix does matter (at least on my system). I ran cif_as_mtz (from 1.8.1-1155) on 3a0n, using only the "--merge" switch. Running from the CIFS mount, it took ~5 minutes. Running from the local file system, it took ~21 seconds. The CIF file was on the local file system in both experiments.
Weird.

CIF and writing the MTZ could be substantial though. Try running a
few jobs with files on a local disk and see if that goes faster.
