Hi Team,

We are having a slow query issue for one of our applications. We are seeing slowness(5 seconds) when we use both ORDER BY and LIMIT 30 clause whereas the same query is performing very good(200 MS) when using only ORDER BY clause.  Also note that the query performed very fast(200 MS) when we increased LIMIT to 100 along with ORDER  BY. 


Can you please help us if there are any bugs related to this?  OR Can someone kindly provide some solution to this issue?
