Same scene.  Same settings.  Radiosity, media, the whole shebang.
3.1 took 00:04:23:51
3.5 took 00:18:56:52

Shouldn't 3.5 be at least as fast, if not faster than, 3.1?

3.1 radiosity should not be compared to 3.5 radiosity since both are
completely different.

...and thus comparing the two with radiosity is like comparing apples and
oranges.  There is simply no use to use features that are marked as
"experimental" to measure speed differences because there will always be
quality differences as well if the experimental features changes (which it
is free to do).

What are good 3.5 radiosity settings to shrink that 14-hour
render time I got?  I think all my settings were the defaults.

  A good start is to put just an empty radiosity block in global settings.
That is:

global_settings
{
  radiosity { }
}

  If the result doesn't look good, you could then try increasing count (for
example to 100) and/or decreasing pretrace_end (to .02 for example).
  If it still doesn't help, then you'll have to start tweaking with other
parameters as well...
