Among others I'm using it to rsync big folders. I had one big problem. On the destination the file system permissions where that wrong, that I could not enter the rsynced folders. As it is said in the internet, the solution for this is to use NOACL as fstab option. But that leads to massive speed slowdown. rsync processes took around 10 times as before. The same for du on a complex directory. Without NOACL it needed in one example 5sec and with NOACL around 10 minutes. So it seems like that the NOACL option leads to problems with file system processes. Whats the reason and is there a solution for that? > >Thank you for helping. Try adding the "notexec" option. If it's mounted "noacl" Cygwin checks for executable by opening the file and checking the two first bytes. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
