I have two machines that show very different performance numbers.
After digging a little I found out that the first machine has, in /proc/cpuinfo:
model name: Intel(R) Celeron(R) M processor 1.00GHz
while the other has:
model name: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
and that seems to be the main difference.
Now the problem is that /proc/cpuinfo is read only. Would it be possible to make /proc/cpuinfo writable so that I could do:
echo -n "model name: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz" > /proc/cpuinfo
in the first machine and get a performance similar to the second machine?
