Is it normal for your Super Pi score to go up with time?

When I first got my computer I got 1min 02seconds on super pi, now I am getting 1min 06seconds. I know it is not a big difference but I am wondering if it is normal for you score to go up with time. I would kind of assume the longer you own your computer the more programs you have installed and running, Hence the longer it would take to complete super pi.

But, with my old HP I did notice significant time increases even with no change in software I mean from 8minutes to about 12 (it was an old celeron), so I'm not positive what caused that increase....

 

I would concur with your diagnosis about other software / processes grabbing an increasing slice of the CPU time. Try shutting down the virus scanner then go into Task Manager and try closing anything which is accumulating significant CPU time.

computers are not precision instruments like many people seem to think. something like superpi needs to be run multiple times over a span of time and the avg taken.

 

But, what would explain such a drastic increase with my HP?

Also, why are computers not precession instruments aren't they designed to be so?

 

I agree with John Ratsey.
Close some unneeded processes down say, run it first thing on boot.

 

what would make you think that they are designed to be so?

 

Heat
Amount of processes
Age

These are some of the things in which would affect the "change" in your scores.

 

I would assume that every time a program is executed it is done so in the exact same way, and baring any software or hardware changes, I would expect the program to be executed in the same amount of time, every time.

This is what I have always thought, let me know if I am incorrect.

I'm not necessarily time to reduce my time back to 1:02 I mean four more seconds isn't that big of a deal.

I was just wondering what factors effect an increase in time.

 

the reason is that windows builds up 'junk' over a long while of use. a lot of this junk ends up wasting resources, temporary files, registry errors, I can go on forever....

I gaurantee you that once you do a clean intsall (reformat HD and reinstall OS), that your superpi score will go back to what it was. Superpi is just timing how long it takes calculate a certain algorithm

 

stop using a single-threaded program... SuperPI

if you have a dual-core or multi-core, use a multi-threaded program that will utilize all the cores....
wPrime.

 

You don't like super pi? I find that it is a nice simple bench marking program.

And aren't most programs still coded to only use one core??

 

Well, it isn't that people don't like super pi, so much as it is a dated benchmark. Since dual cores are main stream now in most notebooks, you might as well run a benchmark that stresses both cores for comparative purposes.

Anyway, wPrime will work as Gophn suggested.

As far as your initial question, it is not really that surprising at all. I agree with what has been said here thus far.
