The T5440 is at the extreme end of T-series NUMA latency. The T5220,
being just one chip, is at the other. Do you have all your vcpus in
one domain? If so, that's a lot more cross calls too! Very few apps
can scale sensibly on that beast and cope with both factors. I guess
DTrace is one of them.
Yes, I'm starting to notice that with our other software also... this is
probably off-topic, but is there a way to hint at Solaris that you'd
prefer it to map your process physical memory from a certain socket?
Processor sets don't seem to do it (they do kill the crosstalk from
x-calls), but I haven't tried domains yet.
