System performance benchmarking tool?
Can anyone recommend a tool that measures, i.e. quantifies performce on a PC?
e.g. exercize the CPU, memory, drives etc and report on their speeds.
I'd like to periodically measure these aspects and compare so I can spot degradation or improvements after making mods.
Thanks, DaveBo
Odd results from home-made test
FWIW I tried writing a home-grown VB app to beat up on the system, e.g. running 30 million int calcs, then 30m FP calcs, consuming memory and doing file IOs while timing everything.
I ran this repeatedly on 4 diff systems and got pretty much the results I expected, with one strange exception below.
Here's the code I used to try to exercize and consume memory, I know it's kind of arbitrary and maybe not meaningful (that's why I'm here. Please suggest something better!)
Code:
Dim BigArray() As Long
Dim x As Long
For x = 1 To 500000
ReDim Preserve BigArray(x)
BigArray(x) = x
Next x
And here's the results, in order of what I thought would be fastest to slowest:
Code:
CPU Speed Mem OS Seconds
P4 2.27GHz 512MB WinXP 1.748
P3 800MHz 256MB Win2K 4.570
P3 800MHz 256MB Win98 0.460
P2 300MHz 64MB Win98 1.340
Any ideas? Are the "more advanced" OSs adding overhead?
Thanks, DaveBo
