During December 2024, Jian Liu focused on performance optimization within the AliceO2Group/O2DPG repository, specifically targeting the ITS MV cycle in the ITS subsystem. He worked to reduce the cycle length, aiming to improve throughput and responsiveness in ITS data processing while maintaining system stability. The internal improvement was documented in commit f4ad96ea1e3ff97020a5e90a392372693b7bd2c9, though no code changes were present in the diff, leaving user-facing impacts under assessment. Jian applied his knowledge of C++ and data processing pipelines, demonstrating a methodical approach to system-level optimization, though the depth of the change remains to be evaluated.
