[SunHELP] Performance Standards

[Theodore White]

I have some performance numbers from a potential client, and wanted to know
what kind of system would be able to handle it? The application is database
driven (Oracle), with the majority of the app being static pages. I hoping
that someone could give me an idea of the kind of machines that I should
think about (The datbase would be on a separate machine, both machines
running Solaris 8, with iPlanet). Sorry if the info is kind of vague (or
not).....

Thanks in advance....
