Hardware

Hello,

Problem Statement:
We have many single threaded applications in our project. Performance of all these processes has been degraded on Netra T2000.
We have also observed performance degradation with simple shell script with just a "for loop: doing assignment of a variable".

Query:
What could be the best possible optimizations that could be done to get better performance?

We have recently moved from Sun Fire V440 to Sun Netra T2000.
Hardware configuration details are mentioned at the end.

We use Jboss Application Server in our project.
Version of Jboss used is 4.0.4.
Startup of Jboss is very slow on Netra T2000.

We tried the tuning parameters mentioned in the below link.
But, there is no improvement in the startup time.

Comparison data is specified below. tests have been performed with the Jboss downloaded from internet. No slimming was done.

Time for startup of Jboss:_
Sun Fire V440: *30 sec*
Sun Netra T2000: *1 min 30 sec*

Configuration of Sun Fire V440:_
SunOS dtcdevsrv1 5.10 Generic_125100-10 sun4u sparc SUNW,Sun-Fire-V440
System Configuration: Sun Microsystems sun4u Sun Fire V440
