Thanks to everyone who contributed (Special thanks to Jay Lessert)

1. Sparc IIIi processors will be comparable (thanks to 1 MB L2 cache) to Sparc
III, for applications which do not require intensive computation processing.
For computation intensive applications like Oracle, Sparc III's external cache
will come in handy. For Weblogic type of applicaiton servers, IIIi could give
85-100% of the performance of III. Actual benchmarking is required to make
final decisions. Sun might relase sun benchmark comparisons this week.
2. Cache is *fuly* used.
*everything* the applications touch, executables and data, are read into cache
before being read by the processor, and
written to the cache before being written to main memory.  So unless process
footprint is < 8MB, you're using it all.

All,
A related question would be : How could you find out the actual usage of the
external cache on your CPUs?
We have 280Rs with 2x900MHz processors (with 8MB external cache each) and I
want to find out how much of the external cache is really getting used. Is it
possible?
Thanks again
BTW, I have gotten couple of feedbacks on the first question and will
eventually summarize the results.

All,
The newly released Sparc IIIi processors have 1MB L2 cache (integrated) but
no
other external cache, compared to 8MB of external cache available in Sparc
III
processors (which have 512K L2 cache).
Any idea how would this affect/improve performance?
Thanks in advance...
