Hi, If you feel the refinement to be too slow, you may turn off the smooth centering (in preferences) or change the centering steps to a smaller number to save unnecessary graphical calculations. To go extreme, you may even remove the real time display commands in the scripts - also a way to test if the difference observed is due to different graphical efficiency. Reducing the size of the displayed map also help.
The other thing you may need to consider is that coot/wincoot will save a backup file each time it updates the model, which means on each step of the refinement you have a new file generated. If your windows disk is terribly fragmented then sure you will spend a lot of time on writing these files. The other thing is, windows has a different file caching mechanism from linux, this can also cause a huge difference when a few hundred small temporary files are queued for writing. My impression is that both the ext2/3 file system and the way linux handles caching are more efficient for this kind of situations. You may try deleting the files in wincoot\coot-backup periodically and defragmenting that partition. Making a virtual disk in the RAM to put your backup directory there could be something to experiment on too.
