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.

package-appclient
package-appclient(1M) Application Server Utility package-appclient(1M)
NAME
package-appclient - packs the application client container libraries and jar files
SYNOPSIS
package-appclient
Use the package-appclient command to pack the application client container libraries and jar files into an appclient.jar file. The created
file is located at appserver_install_dir/lib/appclient/appclient.jar. The appclient.jar file provides an application client container
package targeted at remote hosts that do not contain a server installation.
The appclient.jar archive contains native code and can be used on a target machine that is of similar architecture as the machine where it
was produced. So, for example, an appclient.jar produced on a Solaris SPARC platform cannot be used on a Windows client machine.
After copying the appclient.jar file to a remote location, unjar it to get a set of libraries and jar files in the appclient directory
After unjarring on the client machine, modify appclient_install_dir/config/asenv.conf (asenv.bat for Windows) as follows:
o set AS_WEBSERVICES_LIB to appclient_install_dir/lib
o set AS_NSS to appclient_install_dir/lib (appclient_install_dirin for Windows)
o set AS_IMQ_LIB to appclient_install_dir/imq/lib
o set AS_INSTALL to appclient_install_dir
o set AS_JAVA to your JDK 1.4 home directory
o set AS_ACC_CONFIG to appclient_install_dir/config/sun-acc.xml
Modify appclient_install_dir/config/sun-acc.xml as follows:
o Ensure the DOCTYPE file references appclient_install_dir/lib/dtds
o Ensure that target-server address attribute refrences the server machine.
o Ensure that target-server port attribute refrences the ORB port on the remote machine.
o Ensure that log-service references a log file; if the user wants to put log messages to a log file.
Modify appclient_install_dir/bin/appclient (appclient.bat for Windows) as follows:
o change token %CONFIG_HOME% to appclient_install_dir/config
