At a conference a few days ago, Dr S made a couple of throwaways about the relatively poor performance of cp on gStoreFS file systems. During dinner, a beaker from DKRZ sidled up to him and suggested that everything could be fixed by twiddling a couple of system settings.

Sure enough, once I was informed of the results of my scientific colleague's schmooze-a-thon, I ran a couple of experiments and quickly discovered a setting that cut the time taken by a copy command down from 112 seconds to 2 seconds.

Yikes.
