I am trying to understand why my system is running slowly. I found the sar command, but wanted to know the difference between sar -B and sar -W
I read the man page, and I understand that -B gives me the paging statistics and -W gives me the swapping statistics. What I would like to understand is the following:
What is the correlation between the two sets of statistics.
When should I be concerned about -B and when about -W? ie, what values from each command should I be concerned with?
Which statistic is more closely related to system performance
