Yes, when reassign a simple new corona mtl to all objects it's lightning fast, I should have mentioned it before, this could have speed-up your search, sorry.
[edit] oh and i tried to disable each single feature of all materials one by one (per script) but i couldn't find anything. No maps, no colors, no reflection, refraction, etc... The strange thing here is: it got faster and faster the more objects I was hiding - so, it's something about materials but... not only one specific ;)
[edit2] Btw, i also tested if it's something related to windows (I've got win8 here) - it is not... but maybe it's something related to the cpu generation or something (which could explain why keymaster is not able to reproduce it). Could you share some cpu specs?
mine: 2x E5540 Xeon cpus, other machine (with the same problem) 2x E5530 Xeon cpus

Any sufficiently advanced bug is indistinguishable from a feature.
