Hi folks...
recently I did a simple experiment, that was running a CPU bound program
on Linux kernels with different HZ setting. I pick three, HZ=100,
HZ=250 and HZ=250. Here is the result:
HZ=100 HZ=250 HZ=1000
Real 319.326 317.786 319.072
User 319.33 317.801 319.094
System 0 0.001 0
thats 0.66% - a small enough variation to be just noise.
what happens if you run them each 10 times, do you get similar
variations within each group ?
If you do, try booting to single user (level 1) to eliminate as many
irrelevancies as possible.
