PFA Monitored data on caches under User PFA

The PFA monitoring program records monitored data on caches under User PFA.

User PFA (User Controlled Performant File Access) allows users to assign performance attributes to files, thus converting them into hiperfiles (High Performance Files). The idea behind hiperfiles is that file access is accelerated by buffering the file in a high-speed cache in order to avoid the slow disk input/output operations. Main memory (MM) is used as cache medium.
