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:

The 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.loadbalancer.type=lb
| worker.loadbalancer.balance_workers=node26,node79
| worker.loadbalancer.sticky_session=0

A part of the configration in server.xml in tomcat of JBoss(192.168.13.26) is :
<Connector port="8080" address="${jboss.bind.address}"
| maxThreads="250" strategy="ms"
maxHttpHeaderSize="8192"
| emptySessionPath="true"
| enableLookups="false" redirectPort="8443"
acceptCount="100"
| connectionTimeout="20000"
disableUploadTimeout="true"/>
| <Connector port="8009" address="${jboss.bind.address}"
| emptySessionPath="true" enableLookups="false"
redirectPort="8443"
| scheme="https" protocol="AJP/1.3"/>
| <Connector port="8443" address="${jboss.bind.address}"
| maxThreads="100" strategy="ms"
maxHttpHeaderSize="8192"
| emptySessionPath="true"
| scheme="https" secure="true"
clientAuth="false"
| keystoreFile="${jboss.server.home.dir}/conf/server.keystore"
| connectionTimeout="8000"
| keystorePass="12345678" sslProtocol = "TLS" />
| <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^
