[JDEV] jabber users limit !!

[Steven Fisk]

Vijay,

Regarding your post, I have gotten upwards of 5,500 simultaneous connections
(and over 8,000 open connections according to a netstat -an | grep -c 5222)
to a single jabberd server. I am now in the process of trying to see how
high I can go using a multiple jpolld machines connecting to a single
jabberd server. 

The problem you are having with not surpassing 1024 TCP connections is not
resolved by changing the ulimit, you need to recompile the kernel ( I assume
from your problem you are running Linux ) after changing some header files,
here is a link that is very informative on how to up the connection limits
in the kernel- http://www.volano.com/linuxnotes.html

Hope this helps. I also have had problems with the simulator that is in the
jabber.org CVS, hopefully someone will develop a better one and post it one
of these days...

well mine aim is not 1k User its much more than that I am targetting
1,00,000 users .
but presently I am targetting to get at least 40,000 users SIMULTEOUSLY .
well I think its not 1000 messages per second .
I have putted up message_delay =1000  ,& its a dealy of 1000 seconds for
each users's message .

well offcoz mine aim is not only to test user to maximum no of users it can
take ,but to achive it also some how .
well it would be a great help if anyone has tested jabber for more than 1024
.

well whole aim is to somehow facilitate jabber to support 40,000 TCP
connections
through jpolld ,Ulimit ,server farm ,kernel optimization .

well I think if some how we can achive this it would be a big lap for jabber
community

thanks
