[Web4lib] measuring PC performance

[John Fitzgibbon]

Hi,

We upgraded the operating system of a number of our Internet PCs from
Windows NT 4 to Windows 2000. We added some memory. In some cases
performance dis-improved.

Given all the factors that affect performance, can it be predicted how
changing one element will affect power. For example, RAM, Hard Disk
size, and processor speed all affect power. But what is the relationship
between RAM and power. For example, if I double the RAM what is the
percentage increase in power? Is there an algorithm for determining
this?

Finally, the operating system affects performance. The more recent
operating systems seem to be more resource hungry and require more
powerful computers. Can this be factored into the equation?

Is there a simple means of testing a PCs performance, e.g. getting the
PC to perform a task and timing it? This would help us decide to
increase RAM or not and once RAM is increased has it worked.

Any thoughts would be much appreciated.
