The output of cat /proc/mounts shows that all internal file systems are mounted with relatime option. What I read about it is that there is still some overhead compared to noatime option and is totally useless. noatime would give a little bit of performance gain with no side effects. Does anyone know where this setting come from in Knoppix ? Is it a kernel setting ?
Here is the output of cat /proc/mounts:
