OK, i have seen the output of two runs of "vmstat". What is it that you want to know, now?
"Tuning for performance" is a wide field and if your system is well tuned or not can't be answered from these data.
"Performance" is a term meaning "fitness for a specific purpose". As we don't know which purpose the system serves we can't tell if it is fit for this purpose or not.
If a vehicle is "fast" can only be answered once you specify the details of the movement involved: which streets (streets at all?), how much cargo to transport, distance involved, etc., etc.. The same goes for "performance": one would have to know, which applications the system runs, what it is expected to do and in which time and so on and so on.
And even if we would know which purpose the system serves and what else is running on it, there are still questions left: hardware resources (number of real and logical processors, disks, filesystems, I/O figures, OS version, network connections, .... the list could easily be continued.
Therefore: carefully rephrase your question, thinking over what exactly you want to know, what you already have in terms of data ("vmstat" was sure not the only command you tried, did you?) and what you want to achieve.
Then come back and ask again.
