Does RFS manage virtual paging - or is it just a block of memory?

Unless you are running RFS (for which we have a our own cache in shared
memory), you are likely just experiencing the OS file system cache and
or disk RAID array cache...

Can anyone shed insight on how/what Unidata does for caching?
In short, I notice that when I perform some SELECTs or programs which
read a handful of records, they often run faster after first execution -
I'm assuming Unidata is caching.
I was working on adding some caching to an application I'm working on
but if Unidata is already doing a reasonable job I may not see any
sizable performance difference (and don't want to spend many hours
working on this to find it's in vain...)
Any insight appreciated.
