I would try to get a reduction - can you profile and figure out the
exact part of the simulation that is slower? If it is a specific
function or set of parameters to a function, perhaps we can suggest a
replacement.

In addition to other steps, contact MathWorks technical support.
Assuming that your code is decent, it should run at acceptable speed on
all platforms, or they should have warnings about slow things in the
docs with suggested replacements. Having that reduction I mentioned a
bit ago will help them answer the question.

And platforms do differ - a good LAPACK implementation on a G5 blows
away a similarly clocked Pentium, because the G5 has amazing memory
bandwidth, and a keen vectorized float unit. If the test centers on
integer performance, you will usually get better results on an x86
machine, as they tend to have better integer units. Add in the
excitement of different clock speeds, multi core vs multi chip, quality
of multithread implementations, and it becomes a bit murkier.

Thus, while the best MW tech support can say about certain problems is
'that's how it is', there should be a fair number of problems that they
can say something useful about.
