From [2603.04782] "Unlocking Python's Cores: Hardware Usage and Energy Implications of Removing the GIL" (2026) https://arxiv.org/abs/2603.04782 : > Abstract: [...] The results highlight a trade-off. For parallelizable workloads operating on independent data, the free-threaded build reduces execution time by up to 4 times, with a proportional reduction in energy consumption, and effective multi-core utilization, at the cost of an increase in memory usage. In contrast, sequential workloads do not benefit from removing the GIL and instead show a 13-43% increase in energy consumption
