The performance of JBoss clustering puzzled me
Hi guys:
I?m new to JBoss clustering and apache.
Has anyone met problem like this? I use JBoss cluster to test my JSPs,but its performance was not so great,and even badly than the performace without clustering. Here is my environment:
I have three servers:
The first one (ip:192.168.13.26):
Windows XP sp2
512M memory
JBoss 4.04GA
The second one (ip:192.168.13.2):
Windows XP sp2
256M memory
JBoss 4.04GA
The last one (ip:192.168.13.2):
Windows 2003 Server Enterprise Edition
1G memory
Apache 2.0.59
The compiled in modules of the Apache is:
core.c
mod_win32.c
mpm_winnt.c
http_core.c
mod_so.c
httpd.config of apache on 192.168.13.2:
ServerRoot "C:\Program Files\CSS\Apache2"
PidFile logs/httpd.pid
Timeout 300
KeepAlive On
MaxKeepAliveRequests 0
KeepAliveTimeout 15
<IfModule mpm_winnt.c>
ThreadsPerChild 250
MaxRequestsPerChild 0
</IfModule>

Include conf/mod-jk.confThe workers.properties of apache on 192.168.13.2 is:
worker.list=loadbalancer,status #JBoss on 192.168.13.26 worker.node26.port=8009 worker.node26.host=192.168.13.26 worker.node26.type=ajp13 worker.node26.lbfactor=1 worker.node26.cachesize=10 #JBoss on 192.168.13.79 worker.node79.port=8009 worker.node79.host=192.168.13.79 worker.node79.type=ajp13 worker.node79.lbfactor=1 worker.node79.cachesize=10 worker.loadbalancer.type=lb worker.loadbalancer.balance_workers=node26,node79 worker.loadbalancer.sticky_session=0 worker.status.type=status
A part of the configration in server.xml in tomcat of JBoss(192.168.13.26) is :
<Connector port="8080" address="${jboss.bind.address}"

<Connector port="8443" address="${jboss.bind.address}"

<Engine name="jboss.web" defaultHost="localhost" jvmRoute="node26">I used LoadRunner to record the script of visiting the JSPs in JBoss,and used JProfiler to monitor the JBoss on 192.168.13.26.
I tested three times(50 virtual users visit the JSPs parallely 20 minutes.The CPU time involves the time of starting the JBoss service):
Here is the table of the tests results:

If cann't displayed,see http://picasaweb.google.com/ddpie.flea/JBoss/photo#5063968585782417570.
I doubt apache was the bottleneck,but I don?t know where the problem is with my configration of apache.
Does anyone know?
Thanks in advance.^o^
