------------------
Some activities that StatusNet needs to do, like broadcast OStatus, SMS,
and XMPP messages, can be 'queued' and done by off-line bots instead.
For this to work, you must be able to run long-running offline
processes, either on your main Web server or on another server you
control. (Your other server will still need all the above
prerequisites, with the exception of Apache.) Installing on a separate
server is probably a good idea for high-volume sites.
XMPP messages and TwitterBridge operations, can be 'queued' and done by
off-line bots instead.
Two mechanisms are available to achieve offline operations:
* New embedded OpportunisticQM plugin, which is enabled by default
* Legacy queuedaemon script, which can be enabled via config file.
### OpportunisticQM plugin
This plugin is enabled by default. It tries its best to do background
job during regular HTTP requests, like API or HTML pages calls.
Since queueing system is enabled by default, notices to be broadcasted
will be stored, by default, into DB (table queue_items).
Each time it casn, OpportunisticQM will try to handle some of them.
This is a good solution wether you:
* have no access to command line (shared hosting)
* do not want to deal with long-running PHP process
* run a low trffic GnuSocial instance
In other case, you really should consider using queuedaemon.
### queuedaemon
If you want to use legacy queuedaemon, you must be able to run
long-running offline processes, either on your main Web server or on
another server you control. (Your other server will still need all the
