There is an emulation layer for branded zones so there is some extra overhead that is not needed with native zones. The overhead will vary for each brand and for the various system calls that need emulation. For the s8/9 brands we were careful to keep the emulation overhead low or nonexistent for the most common code paths, so it should generally not be a factor. Plus, you should be moving from slow, obsolete hardware to new, faster hardware (which doesn't run s8/9), so that should more than make up the difference. There are lots of factors that come into play so you really need to measure the performance if it matters.
