Application running too slow on Sun SPARC T5440 but run normal on sun M3000

Hi all,
I have application running on sun server T5440 4x8x1.4 GHz, 64 GB RAM, application running very slow though load average too low. when I install my application on another server SUN M3000 (One CPU 1x8x2.5GHz, 8GB RAM), application run smoothly.

Here is my server T5440 info:

When my application running, some of CPU have IDLE state = 0 and hold the CPU while another CPU have IDLE state 100. I think this is my bottleneck but I cannot find any solution for solve that.

Please help me find the bottleneck of my T5440 server?Thanks so much for all your help.

Niagara CPUs are best suited for massive parallel loads, like webservers. Your machine can run 256 threads in parallel, giving each thread 1/256th of the overall computing power. But the single thread power is quite low, especially on early Niagara type CPUs, like the T1 and T2.

It seems, your application is composed of a few single threaded programs where each programm runs on a single virtual CPU, leaving most of the computing power unused. Such applications are not very well suited for a Niagara CPU server.

Your application runs well on the M3000, because the SPARC64 CPUs are designed for only few threads with a lot of computing power per thread.

Sun's Rock CPU was supposed to close the gap between those two architectures, but was never brought to market. The new T4 CPU seems to come close to this goal.

Have any solution to migrate thread power to some thread on the same cpu.
For example: i have 4 cpu and 64 thread on each cpu. i offline 56 thread on each cpu and my system have 32 thread online on 4 cpu. or tell me some solution for this?
Many thanks for your help.

You can take processors offline with the psradm command, look at the manpage to get the details.

But that would not speed up your program, switching off unused cores does not make the remaining ones faster. You have to change your programs instead, if possible, to utilize more threads.

My application is a third-party application so i can't change, please help me find any process, thread or commands of OS in my application using a lot of computing power on thread . I can request my software vendors to review it.
Many thanks for your help.

I am not aware of any way to combine the computing power of several cores for one single thread, it's just how the CPU is designed.
