I'm using jabber as the socket-communication layer in a
multiplayer game platform. I need it to perform much better than
what I'm seeing. I'm looking to bring someone in as a freelancer
to help me set up a jabber environment that meets the
requirements below. You should be an expert admin on one of the
open source jabbers (mainly looking at jabber1, and ejabberd so
far). If you're interested email me with your rate, resume, etc.
at larry.kirschner at mtvn.com. There's a crunch to get this done so
it'd be great if you're available immediately. I'm guessing this
will be a few days to a week or so of work. On the other hand if
you're not looking for work but just want to chime in, any
help/advice is greatly appreciated. REQUIREMENTS: * 10000
concurrent users* Users grouped into muc rooms in groups of 5 to
20* 10000 (muc) messages/second (these will mostly come from the
GAME_SERVER user who will broadcast game events over a small pool
of connections)* Small number of rooms with many users (500+).
These are the game lobbies. Message rate to lobby rooms will be
much lower than message rate to game rooms, mostly just
LOBBY_ENTER and LOBBY_EXIT messages* Ability to support flash
0-byte XmlSocket connections Because of the flash requirement,
I've been using jabber1.4, but it's not performing anywhere near
the way I need it to. Instead it seems to be limiting messages to
about 1 every 2 seconds and dropping (rather than delaying)
messages sent in the interum. The current DEV deployment
is: jabber 1.4.3muc 0.6.0jadc2s 0.9.0 (connected as a service on
the same box as jabberd) DEV box is linux 2.6.9 with a single
Intel Xeon 3.06GHz and 1GB ram. The production env box is beefier
with 4 procs. I haven't been able to figure out what's causing
the poor performance. I have all karma turned off and debug
turned on. I'm very open to trying other open-source jabbers if
they have a patch to work with flash XmlSockets. Ejabberd in
particular looks like it would be a great fit for this platform.
I've been looking around for an ejabberd/flash-socket patch, but
all I find is lots of mail-list requests like this one asking for
the patch. Thanks, Larry KirschnerSoftware ArchitectMTV Networks
