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. > Most peculiar....although I think but I do not know whether the linux > binaries are 64 bit 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 Marcin
