I'm afraid that still doesn't quite make sense to me.

csync.cfg:

    include /usr/ports/packages;


# time csync2 -cr /usr/ports/packages
real	0m1.097s

# time csync2 -cr  /
real	1m15.614s


It does not appear to be respecting the includes with respect to the folders it is scanning. Perhaps they will never be added to the DB, but the above simple test seems to show that csync to scanning through lots of files which it doesn't need to. This is a problem with respect to load and speed in our use.


Are you expecting that we need to pass on the command line to -c a list of every folder that we want csync to scan, even though they are already included in the 'include' configuration command?

One of the big drawcards of csync over rsync was the fact that the config is neatly contained in one configuration file.

Thanks

Ari
