I need to measure each core on a T1000 what tool can I use?

I posted this in the hardware zone by accident...I have a multi-threaded app running on a T1000 and I need to measure each core and see if I have equal cpu performance with respect to cpu percentage and memory.Is there a version of top that will do this or ?
# 1
Can you use 'mpstat' and just sum across the virtual portions of each core yourself?
Most of the tools that come with solaris were written when all CPUs were real (or at least real cores) and don't understand the distinction between silicon and hyperthreading.
If you have a recent enough version of Solaris, kstat should have some 'core' designators to help match up the virtual portions.

corestat.
Get it from http://blogs.sun.com/roller/resources/travi/corestat_v1.0.tar.gz. More information at Ravindra's blog: http://blogs.sun.com/travi/#Corestat

Note that lower average core utilization doesn't necessarily mean that you can add more load to the system. Refer to http://blogs.sun.com/travi/entry/ultrasparc_t1_utilization_explained, blog entry for related information.
