jboss 5.1 slower 10% than jboss4.2

mlw5415 Aug 12, 2010 4:20 AM

I'm planning to migration from jboss 4.2.2 to jboss 5.1, but it seams that jboss 5 is very slow when I do a test:

env:

os:RHEL 5 64bit

cpu: 2 X Intel Xeon E5310

mem:8GB

jdk:jdk6u21

jboss4.2 vs jboss5.1 ( 50% slower):

url	jboss5.1.0(RPS)	jboss4.2.2(RPS)	result
/mservices/weather/provinces.action	516	492	0.05

jboss4.2 vs jboss5.1 update JBoss EJB3 Plugin 1.0.19 ( 5% slower):

It's good to see that the EJB3 plugin improves the performance to that level.

However, I'm not sure what those values in those tables indicate. For example, what does a negative value indicate? Also have you checked (using some profiler or some other means) what exactly is degrading the performance?

jaikiran pai :

I use apache ab to test,
"RPS" mean "Requests Number per second",
the value of "result" column mean performance improving rate , "0.05" mean 5 percent improving, "-0.05" mean 5 percent degrading.
