In Solaris, it is pi,po and sr columns which may be considered as direct indicators for addressing memory pressure. So you are checking the right columns.
But you also need to check the swapping activity.. (by running vmstat with -S argument) .. The si and so operations...
I see a decrease in you free pages.. Those values are in KBs..  But, you should still have around 17GB free memory there. So I don't think you are running out of memory, but you got a memory demand..
Having a memory demand is not a bad thing in all the cases.. These Operating Systems are designed to page out and page in.. We don't just copy all the code into the memory in one go and we always try to be ready for a future shortage..

3-21? 1-10? How do you conclude that?
Especially the SR column.. Please send me a easy-to-read output for the values of these SR column.(+ Si,SO,Pİ and PO)
Normally, The sr column under the page column indicates the scan rate. High scan rates are caused by a shortage of available memory. YES.. However; we got around 17Gb free memory there.. Normally those scans are started when the server reaches the "lotsfree".. It is set to 1/64  of the physical memory.. (unless you modified it somehow)
