Re: swapinfo
From this output ur usage seems to be fine.
No problem for me(OK its not question about me :) but if everything is fine why u wanna reduce PERCENT USAGE???
Best way is to add lot of swap space...so % usage would be low.

Re: swapinfo
Agreed with Denis, we usually use
swapinfo -tam
if you total memory used > 70%, you seems to have memory pressure.
Hope this help

Re: swapinfo
I think thu culprit here is the buffercache. Your system is experiencing a slight memory pressure. You should lower the buffercache. Reduce the dbc_max_pct kernel parameter to something around 5% . This should improve the behavior of your system.
