Couldn't help but reading an old post regarding Corona's optimization...

Imho comparing Vray and corona is a bit nonsense (yet). Both are using kind of different concepts to render the image. For me, Vrays DMC is way more useable in daily business than coronas current concept of (simply spoken) just shooting rays without any adaptivity. You can do really awesome things in Vray, especially in terms of speed/quality if you know how DMC works. Don't get me wrong, I love corona, but until there is some possibility to tell corona not-to-shoot-a-lot-of-rays-in-already-clean-areas I don't see a lot of sense in comparing the two. Sure Pathtracers always rock in terms of speed/realism, but there are a lot more things a good renderer should be able to do and at some point those pathtracers just are not the right way to go.
If you really want to compare Vray to Corona for interior you may want to try PT+HDCache for Corona and BF+Lightcache for Vray - which is at least kind of the same concept.
