Please tell us where these values came from - we need to know the
source of the values in the table.
vmstat is a system tool, prstat is a process/thread tool.
vmstat will tell you how much memory is free from the kernel's perspective.
prstat will tell you how much memory is being used per-proces
When calculate and compare the memory usage when
a Application starts, with "prstat" and "vmstat".
We found 384MB memory gap.
Timing| Memory Used |Free Memory |
--+---++
Before start App 'A' | 1648MB |
