Abstract: A computing system operates according to a method including: identifying a code difference set representing a difference in a first code and a second code, wherein the first code corresponds to a first application and the second code corresponds to a second application subsequent to the first application; determining a first performance metric and a second performance metric, wherein the first performance metric is associated with executing the first application and the second performance metric is associated with executing the second application; determining a target code portion based on comparing the first performance metric and the second performance metric, wherein the target code portion is a portion of the code difference set representing an estimated cause for a regression associated with a difference between the first performance metric and the second performance metric; and generating an adjustment task based on the target code portion for addressing the regression.
