Since 2008, SIGPLAN has selected papers from its sponsored conferences that are of high quality and broad appeal. These papers, called SIGPLAN Research Highlights, are selected by a committee representing SIGPLAN's major conferences and elected officials.  Four papers were selected by the committee as SIGPLAN Research Highlights in 2019.

This paper makes a substantial improvement to the state of production performance profiling tools.  The paper is widely accessible and will be of interest to application, tool, and system developers … Application and system developers will want to use it.
