Thanks all replies and your valuable comment.  I agreed most of us that
email application is not CPU-intensive but I/O.  A large CPU cache that
crunching a common set of data in memory fast may not help in this aspect.
At the same time, we are moving the mailbox to a new SAN storage array
that increase the total IO throughput.  As our 280R (750MHz UltraSPARC-III)
was a bit dated and it is time to look for replacement.  Most would suggest
V440 for price/performance reason and I probably go for it.
