It's not that astonishing IMO, since you are using several light sources,
reflection, complex objects, ...

Maybe try turning off those things one after the other and check the
render time.  

BTW, the wood texture looks a bit strange with the concentric rings
(normal?)

Yes, you have to add '+qr' to turn it on in addition to the radiosity{}
block.
