# Salt caches the list of files/symlinks/directories for each fileserver backend
# and environment as they are requested, to guard against a performance bottleneck
# at scale when many minions all ask the fileserver which files are available
# simultaneously. This configuration parameter allows for the max age of that
# cache to be altered.
#
# Set this value to 0 to disable use of this cache altogether, but keep in mind
# that this may increase the CPU load on the master when running a highstate on
# a large number of minions.
#
# Rather than altering this configuration parameter, it may be advisable to use
# the fileserver.clear_list_cache runner to clear these caches.

# The fileserver can fire events off every time the fileserver is updated,
# these are disabled by default, but can be easily turned on by setting this
