That depends on what you mean by "paging". Since code on JFS or JFS2
in AIX is readonly, it is not necessary to pageout code, only to
pagein. And since I only need to pagein, code is only paged from the
filesystem. Code on NFS behaves differently.

I suppose your query is whether all the paging activity involves the
paging space? Well answer to this one is No. Only working storage
pages use the paging space. All the permanent storage pages use the
file space instead. Pls check vmstat -s to find out stats on total
page in/out (includes paging space as well as file space) and the
paging space pages in/out.
