Ok, there is probably some differences due to version of kernels:
The first (old) was a 2.6.26-686 (Debian Lenny) and the actual
is a 2.6.32-amd64.

There is a difference between the output of the command:
vzsplit -n 3
in the same host. but under 32bit
kernel than under 64bit kernel.

Curiously, some value are smaller than before...
less than one percent. I guess that's integer rounding
errors..

But at all, most of this values are much larger.
