Fabio contributed to the ntop/nDPI repository by stabilizing and optimizing statistics handling in ndpiReader, focusing on memory management and multithreading in C. He refactored the statistics lifecycle to enable safer reuse of data structures during duration-based live captures, reducing memory leaks and segmentation faults. Fabio also improved memory efficiency by dynamically allocating flow information fields based on IP version, lowering RAM usage for high-flow scenarios. Additionally, he enhanced cross-platform reliability by resolving MinGW-specific build issues in unit tests, ensuring stable Windows CI runs. His work demonstrated depth in debugging, system optimization, and robust code refactoring for network programming.

Jul 1, 2025July 2025 performance summary for ntop/nDPI: Implemented a memory-optimized refactor by making ndpi_flow_info's src_name and dst_name dynamically allocated based on IP version. This eliminates pre-allocated IPv6 buffers when not needed, reducing RAM usage significantly. The change includes null-pointer safety checks and proper deallocation when flow info is freed, improving safety and reliability under high-load conditions. Commit reference: 4eff2cdb9991eed51e7e00e4dcc2f5fa1955cf17 ("Refactor: make src_name/dst_name dynamically allocated to reduce RAM usage (#2908)").
