Could you please elaborate your statement - "I checked and its reflected lot of SQL Queries."
Where are you getting this and what makes you to come to a conclusion that SQL queries (of Wily or Application Server ? ) are impacting your application ?
Application slowness could be due to many ways or reasons. You need to check the Heap configurations and other parameters at a box level. [ Infra monitoring]
Above is just a drop from an ocean, so please provide more data points so that we could suggest.
