>>> Didn't someone post profiler results fingering MD5 as a bottleneck?
I do have the profile where the md5 was a bottleneck earlier but after changing

Hi Sylvain, Plz find the attachement it is a 3 node setup and i am doing very 
basic thing (including index scan). I can run let the secondary index test run 
longer if you want.
