Are there any metric regarding the performance differences between 12c and 11g?
If you took a single instance 11g database server, exported the data, uninstalled 11g, then installed 12c and imported the data, would it run faster, slower or about the same.
What would you expect if you used the same hardware, exactly the same data / plsql code and same initialization parameters?
Has anyone done any sort of comparison? OS and hardware doesn't really matter, I am just trying to get a ballpark idea.
