If you're working on older hardware with no support for isolation, a lot 
of memory management tasks had to be re-implemented in software, 
significantly reducing performance.  Even with hardware virtualization, 
there is still a lot of needless additional overhead in emulating 
hardware.  However, the previous threads you were likely reading were 
less to do with any performance, and more to do with going through a lot 
of extra hassle and complication for no real gain.

In any case, it was just an off-topic joke, not the cause of the 
discrepancy, and I have no intention to continue the debate further in 
this thread.

Actually, that's not at all the case.  There is no such thing as 
frontend and backend setup.  Rather there is setup that occurs in 
mythfrontend, and setup that occurs in mythtv-setup.  The separation has 
nothing to do with what part of MythTV it applies to, and primarily to 
do with whether or not the changes will require special hardware access, 
or a restart of various applications to take effect.  That is why 
mythtv-setup suggests that you terminate the backend when it opens and 
finds it running.  Anything in mythfrontend can be changed on-the-fly, 
while most things in mythtv-setup cannot, and those that can are placed 
there for logical proximity to those that cannot.
