Thanks for benchmarking.
If you'd like to test refmac 5.7 that will be included in CCP4 6.3
I can make pre-release binaries later this week and put it on ftp.
(I suppose it won't be slower than Linux version, but we'll see.)
One thing that slows down *both* Linux and Windows version is
the GFORTRAN_UNBUFFERED_ALL env. variable.
It was set as a temporary workaround in ver. 6.2, but has been already
removed from the coming release.
If you unset it for refmac from 6.2 you can get a few lines in the output
(in terminal) in wrong order, but the program should run notably faster.

If it's from CCP4 it's 32-bit.
You can check it by typing "file /path/to/binary".
You'll get in the output either
ELF 32-bit LSB executable
or
ELF 64-bit LSB executable
