Cache Application and RPS (request per second).

I’m maybe the last one to discover it :- ). As part of improving web application from 3 RPS to 120 RPS we cache some VO’s (value object) that shared between application pages. Just to check the impact of caching VO’s we add them to the Application items collection but I asked the team to move those VO’s into Cache. What surprise me that while the VO’s stored in the Application RPS reach about 60 RPS but when VO’s moved into Cache application RPS reached up to 100 RPS.
