===============================================================================

Gamin will only provide realtime notification of changes for at most n files,
where n is the minimum value between (kern.maxfiles * 0.7) and
(kern.maxfilesperproc - 200). Beyond that limit, files will be polled.

If you often open several large folders with Nautilus, you might want to
increase the kern.maxfiles tunable (you do not need to set
kern.maxfilesperproc, since it is computed at boot time from kern.maxfiles).

For a typical desktop, add the following line to /boot/loader.conf, then
reboot the system:

    kern.maxfiles="25000"

The behavior of gamin can be controlled via the various gaminrc files.
See http://www.gnome.org/~veillard/gamin/config.html on how to create
these files.  In particular, if you find gam_server is taking up too much
CPU time polling for changes, something like the following may help
in one of the gaminrc files:

# reduce polling frequency to once per 10 seconds
# for UFS file systems in order to lower CPU load
fsset ufs poll 10

Improve the kqueue backend: - also use kqueue to monitor files within a monitored directory - tremendously improve the scalability of the backend when monitoring very large directories - periodically attempt to switch polled files to kqueue notification - do not perform an extra useless lstat() when a missing file is created - code cleanups Approved by: marcus 2005-05-09 17:46:39 +02:00			`===============================================================================`

Fix a number of long-standing bugs with gamin. * Do not use kernel notifications for paths like /mnt and /media. This will allow such volumes to be unmounted. This matches the behvaior of Linux. * Allow the "poll" directive in gaminrc files to have an effect. * Add some verbiage to pkg-message to instruct users how to configure gamin [1] PR: 131121 [1] Submitted by: Graham Todd <gtodd@bellanet.org> (based on) [1] Reported by: countless users Approved by: portmgr (implicit) 2009-04-16 19:32:57 +02:00			`The behavior of gamin can be controlled via the various gaminrc files.`
