Abstract: Systems, methods and articles of manufacture are disclosed for optimizing execution of an application. A plurality of code regions of the application may be instrumented with annotations for generating profile data for each of the plurality of code regions. Profile data for each of the plurality of code regions may be generated via executing the application having instrumented code regions. A delinquent code region may be identified based on the generated profile data for each of the plurality of code regions. A plurality of code sub-regions of the identified delinquent code region may be instrumented with annotations for generating profile data for each of the plurality of code sub-regions. Profile data for each of the plurality of code sub-regions may be generated via executing the application having instrumented code sub-regions. A delinquent code sub-region may be identified based on the generated profile data for each of the plurality of code sub-regions. Execution of the application may be optimized using the identified delinquent code sub-region.
