Wanted to ask, maybe stupid question, maybe somebody can explain me. I installed identical latest Debian 64bit systems on server with E5620 and old test machine with 3040 cpus.
On 3040 1.8Ghz cpu Dom0 without VM usage was:
Mem:  156528k used,   401388k free
After I limited in kernel 500mb aprox. it stayed the same after reboot.

In new server with E5620 usage after boot was 1507816k used. After I limited to 1.7Gb aprox:
Mem:   1828700k total,   251204k used,  1577496k free,

Bouth systems is updated and the same installed with same kernel: 2.6.32-5-xen-amd64 #1 SMP Mon Jan 16 20:48:30 UTC 2012 x86_64 GNU/Linux

Why usage of ram is different and after limitation it used less?
