Is there a standard EPICS CA/PA or V3/V4/V7 performance test scenario or tools, or even results?There have been various performance measurements made over the years, and we even collected some results about individual VME CPU boards, but those results aren't terribly meaningful nowadays (the last result recorded was measured in 2007) and the code we used will probably need work to get it to build on recent EPICS releases. This thread has some information about that application, the measurements are in the performApp/TIMING text file. In other form of question, "do we have the standard procedure to see deployed IOC limitation?"No. I guess most people see whether it's fast enough for their application and restructure or adjust it until it is. In other form of question, "do we have a benchmark tool for any IOC or application?"Base builds a program called catime which measures the performance of a CA client/server connection (there are some instructions on how to run it in the CA reference documentation). Other tests have been performed by various people over the years and described in tech-talk messages or talks at collaboration meetings, but we don't have a standard as such.
