I wanted to test how long it takes for chkpnt/restore to complete.
Trying to determine time vs ram

1. test:
tmpfs with 350MB urandom/zero file
-->chkpnt: 81sec
-->restore: 86sec
-->dumpsize: 340MB

2. test:
C-program that allocates 660MB
-->chkpnt: 26sec
-->restore: 22sec
-->dumpsize: 660MB

3. test:
installed mysql-server (140MB)
-->chkpnt: 0.5sec
-->restore: 4sec
-->dumpsize: 30MB

My questions are:
How does openVZ generate the dump files?
Is there a difference between allocated/used memory?

It seems to me that it depends on which type of data is in RAM for the size of the dump and the time it takes.

Thanks alot for clearing this up for me!
