Test your PC's speed -

namida12 · 10-25-2007, 06:07 PM

Posted elseware - thought you might like to try this simple test...
On second thought it might be old news...

Test your PC's speed, by calculating Pi to 5000 decimal places, using the bc program

time echo "scale=5000; 4*a(1)" | bc -l ; echo `egrep "name|MHz" /proc/cpuinfo ; egrep "MemT" /proc/meminfo`

Inspiration from http://www.geekronomicon.com/?q=node/79 , manpage of bc (around line 310)
and a Dutch site (tweakers.net). Added the egrep stuff to put it in perspective.

Caveat: bc will only use a single CPU.

My results: With a Fry's $88 motherboard and CPU combo

That's a Tyan Thunder (pretty old) dual processor mobo w/ a pair of Athlon 1200's. Even though top showed bc taking 80+% of my CPU, the box didn't slow down.

Edit: Make that

I have only used linux since May, and I liked the windows test site "pcpitstop.com" but have never located a Linux test website equilivent, something I would like to discover...

Using this Test does provide some system processing comparisons, but I do miss the comparisons information that was provided at the pcpitstop location. Another website comparison I would like to see for the Linux community is one similar to Speedfan's S.M.A.R.T.'s hard drive health comparison data base...

I Have written to them, asking if they would add Linux testing but guess it will take many thousands of requests, or a new website established for Linux only...

Not having the database that these two websites have created, would short change the results, but seeing you compare your systems makes me think about these two useful tools I used with the other brand O/S...

The information returned here by "sys" seems to be pretty off the wall, judging by these posts. I would assume that should be returning the actual processor time, but apparently it is not.

Here's another thread with a similar test.

pwc101 · 10-26-2007, 12:50 PM

This is on an IBM T40:

Code:

real    1m14.084s
user    1m13.545s
sys     0m0.048s
model name : Intel(R) Pentium(R) M processor 1500MHz cpu MHz : 1495.208 
MemTotal: 514640 kB

Not amazing, not terrible.

Curiously, if you do this in zsh instead of bash, it spits out the time each process took:

Code:

echo "scale=5000; 4*a(1)"  0.00s user 0.00s system 0% cpu 0.004 total
bc -l  73.64s user 0.06s system 99% cpu 1:14.28 total
model name : Intel(R) Pentium(R) M processor 1500MHz cpu MHz : 1495.208

I actually do have 3 systems, and will be editing my first post to include the results from them, but the first 3 times were all done on the same hardware with 3 different distros. I wanted to benchmark Kubuntu 32-bit vs Kubuntu 64-bit and Kubuntu vs Arch Linux. Not surprisingly, Arch is faster than Kubuntu, but surprisingly the 64-bit processing time isn't all that much faster than the 32-bit.
