hardware comparison question

Managers,

I need to make a hardware replacement decision for a student laboratory,
where 12-14 users on Sun Rays using CDE are running Matlab7.2 with
Simulink6, and some random mixture of: Acroreads, Firefoxes, and Gnu
Emacsen. At the same time, a significant number of remote ssh users
(30-100) also access the machine, running Emacs and spawning occasional
compilations in C/C++. The machine is also driving these 12-14 Sun Rays
and an Apache server, but the main load is generated by the Matlab.
Even though the users are not making any heavy computations, the startup
and response times are pretty bad currently (current configuration is:
E450 with 4x300MHz USII, 3GB RAM).

My problem is to estimate the relative gains achieved by replacing the
E450 with either of the following:

1. E4500 14x400MHz, 8GB RAM

2. V480 4x900MHz, 8GB RAM

Can someone help me with estimating the possible % speedup gained by
moving to either of these configurations, or, at least, compare the
relative % advantage of the V480 over the E4500 for the above load?
Wild speculations are acceptable and welcome.

The assumption is to stick with the Solaris/SPARC platform.

Thank you,
