Identify Recommended System Requirements

We recently changed some of our system requirements in a lightweight application (this is essentially a gui thin client that connects to the mainframe that runs IBM UniVerse). We did not change our minimum requirements at all, but changed our recommended requirements in accordance with the requirements of Windows 7 and Vista (since we are starting these machines).

Some system requirements are fairly easy to determine (for example, a network card, hard disk space, etc.). But CPU and RAM are harder to beat.

Our current list of minimum CPU and RAM requirements indicates that you must meet the minimum requirements for your operating system. This seems reasonable enough to us, since our application uses only 15 MB or active memory and a very small processor (in this case it is a simple graphical interface), so this works. It seems perfect, no one complains about it.

However, when it comes to recommended requirements, we are faced with problems, especially these days, when we say that at least 1.6 GHz (or similar) can mean anything when you start talking about multi-core processors, atomic processors, etc. d .... The thin client starts to do more intense things (now it contains a built-in web browser to help display more convenient html pages, for example).

  • What would be a good way to determine the recommended values ​​for CPU and RAM?
  • Do you take the recommended O / S and add your usage values ​​on top (so we say 1 GB for Vista machines?)?
  • Is there a better way to do this?

(Note: this seems like a server question here , but from the application database instead)

Try it from a different perspective.

First, test your application on a machine with a minimal configuration. What are the bottlenecks, if any?

  • Does it cause a lot of disk sharing? If so, you need more RAM.

One example is Dell, which I use to enter this parameter. This is a two-year-old car, but is still registering 4.2 by experience index. Most business class cars should be able to register at least 3; which should be enough horsepower for the application you describe.

By the way, my 5-year-old laptop is registered as 2.0, and it was average at the time I bought it.
