[JDEV] jabber users limit !!

[Vijay Kumar]

RE: [JDEV] jabber users limit !!Still million $ question is how to configure
& tune jabber to reach its maximum users limit (40,000) .

yha when I also tried to use jabber without jpolld I got around 1113 users
,then I tried to change the TCP limit by ulimit to 32K
which is default to 1024
as
"
echo 32768 > /proc/sys/fs/file-max
echo 65536 > /proc/sys/fs/inode-max
ulimit -n 32768

"
but every time mine client got crased before reaching even to count of 1000
well offcoz just before crash both client & server were around 100 % usage
of CPU .

earlier I also tired to configure the jpolld to other machine (non
jabberd )but everytime I got the "server
configuration error" when ever I tried to connect to jabberd m/c with jpolld
. so for this reason I hasd to put jabberd
& jpolld on the same M/C .
    For last 2 weeks I am doing R&D only on this thing ,that is how to set
up & configure jabber to support maximum
users at a time (40,000) at least . If there is any document on this thing
then I would be a great help .

thanx
vijay

Similar results here.
On a clean P-III 600 w/ 128MB RAM running RH6.2 (.14 kernel) we got up to
1020 users w/o jpolld.  Adding jpolld to the same server brought us down to
around 720.  Appeared to be CPU power issues (98% usage or so), RAM was
fine.  We're in the midst of trying jpolld on one box and jabberd on
another.
I don't have input yet, but I _know_ there's lots of people out there
running jpolld with positive results.  Speak up!

Hi all !!
 I was testing jabberd for maximum no of simultanious user it can support
.To mine surprise I found that it was only able to reach
 around 500 users .Pl tell me what architecture I have to follow to increase
no of user it support.
 mine machine architecture for jabber is .
 |--------------------------------------|
 |                  Jabberd                           |
 |                  Jpolld                              | (Machine 1)
 | (192.168.1.7)                                   |
 | PIII 550 (256 RAM)                        |
 |--------------------------------------|
                        |
                        |
 |--------------------------------------   |
 |  simulator                                             |
 |     (192.168.1.29)                                |(machine 2)
 |---------------------------------------  |
 It only support around 550 users at a time after that system crases
(Machine 1),I tried it many times .Just before crash CPU usase
   is around 100% for machine 1 summing up for Jpolld and Jabberd.I am using
Red hat 7.0 (kernel 2.2.14) .


In jabber.xml I have removed c2s standard to following for jpolld.
<!-- Service to manage incoming client socket connections. -->
  <service id="c2s">
   <host>jpolld.192.168.1.7</host>
        <accept>
          <ip/>
          <port>5225</port>
          <secret>test</secret>
        </accept>
  </service>



& on machine 2
this are the entries for simulate.cfg
"server=192.168.1.7
server_name=192.168.1.7
port=5222
users=1000
message_delay=1
login_delay=1
login_duration=300000
user_letter=r
message=Hi There
"
   Pl tell me what architecture I have to follow to increase no of user it
support .I tries to run jpolld from different machine but
each time I was given "server configuration error " .
   what I have to do so that  I can reach some how even half of tested
(tested up to 40,000 concurrent active users already as claimed by
jabber.org)
