--- Comment #5 from Björn Jacke <bja...@samba.org> ---
how about adding an option like "--use-ctime-before-xattr-compares", which only
reads and compares EAs for files where the ctime on the source side is newer
than the ctime on the target side. EA modifications update the ctime ususally.
This would be a way to speed up syncing with EAs quite a lot I think.

A first work in progress patch to add a hashtable
I need to clean this up and do more tests.
But with 1000 unique xattrs I got 50% less cpu instruction in callgrind.

Possible patch for master
I hope this is an acceptable patchset to fix the problem for rsync master.
