DJXPerf: Identifying Memory Inefficiencies via Object-Centric Profiling for Java

PROCEEDINGS OF THE 21ST ACM/IEEE INTERNATIONAL SYMPOSIUM ON CODE GENERATION AND OPTIMIZATION, CGO 2023, pp. 81–94.

By: B. Li n, P. Su *, M. Chabbi, S. Jiao n & X. Liu n

author keywords: Java; profiling; performance optimization; PMU
TL;DR: DJXPerf is presented, a lightweight, object-centric memory profiler for Java, which associates memory-hierarchy performance metrics (e.g., cache/TLB misses) with Java objects and presents Java object allocation contexts combined with their usage contexts and presents them ordered by the poor locality behaviors.

DroidPerf: Profiling Memory Objects on Android Devices

PROCEEDINGS OF THE 29TH ANNUAL INTERNATIONAL CONFERENCE ON MOBILE COMPUTING AND NETWORKING, MOBICOM 2023, pp. 75–89.

By: B. Li n, Q. Zhao n, S. Jiao n & X. Liu n

author keywords: Profiling; memory inefficiencies; performance; Android
TL;DR: DroidPerf is developed, a lightweight, object-centric memory profiler for ART, which associates memory inefficiencies with objects created and used in Android apps and is able to guide locality optimization on memory layouts, access patterns, and allocation patterns. (via Semantic Scholar)

OJXPerf: Featherlight Object Replica Detection for Java Programs

2022 ACM/IEEE 44TH INTERNATIONAL CONFERENCE ON SOFTWARE ENGINEERING (ICSE 2022), pp. 1558–1570.

By: B. Li n, H. Xu *, Q. Zhao n, P. Su *, M. Chabbi *, S. Jiao n, X. Liu n

TL;DR: OJXPerf, a lightweight sampling-based profiler, which probabilistically identifies identical objects with code-level attribution can assist developers in refactoring code to eliminate object bloat, and favor reuse of existing object(s). (via Semantic Scholar)
