Answer / ashu_jsr
Cluster Index will be faster because data is already sorted
wrt to the index, hence you get the absolute position of
the data, where as in case of noncluster index the relative
position is given by the index

Answer / shaurabh thapa
Cluster Index is faster because it has data in the leaf
nodes along with the key. Non cluster on the other hand uses
cluster index key to search the data and therefore
relatively less fast.
