Strange hackbench test results

[Juergen Beisert <juergen127@xxxxxxxxxxxxxx>]

Hi all,

I trying to work with codesourcery's ARM NPTL toolchain. I made a little test 
with "hackbench" on my 260MHz ARM-PXA processor:

When I use my old toolchain (gcc 4.0.2 and Linux threads) and a 2.6.15 kernel 
"hackbench" outputs:
 6.036

When I use codesourcery's toolchain with the same 2.6.15 kernel "hackbench" 
outputs:
 23.367

While "hackbench" was running there was no other task running on my target nor 
any network traffic.

Its a strange result, where I made a mistake?

Thanks in advance for any hint
