Subject Performance disparity, problem found


Hi, all

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?

/proc/cpuinfo 에는 model name외에도 다른 정보들이 있는데
model name만 넣어주면 되다니 거짓말입니다.

다른 정보도 넣어주여야 됩니다.
