Dear all,
One of the users here is of the view that system is running slow as compared to what it used to run 6 months back.
The server system is sunfire3800.
I have not worked much on performance analysis as such. So wasn't able to figure out much. I asked the user to run is job & noted the output of vmstat, iostat & sar which is as follows.
Can you help me with identifying naything wrong or out of the limit values from the following:
