vmstat

Hi,
what does mean the free colomne in out put of vmstat ? is it free espace of physical memory or of swap space on hard disk ?
Thank you

Look at the output carefully. The swap column has the swap space available. The free is the size of the free list in Kbytes.

Thank you.
But what is free list ? Is it on physical memory or on disk ?

It is free memory (RAM) on your system.
Compare this number with the "free" memory number from the 4th row (Memory) of "top" utility.
