vray area light excedingly slow? RC4

Hi all,
is it me, or RC4 vray area light are slower, by default?

I have been working with HDRI exteriors, and directional lights, for awhile, and now I am back to interior scenes, since I updated to RC4, and a couple of vray area light, in a strip down scene (basic materials), takes for ever to render the smallest test (1000x750)…

Just wondering if anything new was done to vray area lights RC4…

Thank you

regards
