Yes, we have heard this report several times. We know process startup
is slower on Solaris that other operating systems. How much of your
testing is related to starting a new process? Other than that, we think
perhaps the sheer weight of Solaris is slowing us down, though we don't
have any hard answers to give you.

Sorry. I would rather have given a better answer. We are willing to
work with you to idenfity the parts that are slowest and see if we can
somehow work around them.
