Ahem.
 
What wasn't elaborated on is what else the Alpha was doing. Is the application
X windows based? (Eg is the alpha not only running the application but also
serving X terminals?) How complex is the database on the Alpha? What language
is the application written in? Is the Alpha doing anything else at the same
time?
 
Just as an example of extreme silliness, you can run 200 users on a Pentium 90
with 64mb ram and mSql and still not max it out.
 
That's why these numbers are quite meaningless without some details.
 
Details, dammit! :-)
