The ccbench results look pretty good: about 18.1x speed-up on "pi calculation" and 19.8x speed-up on "regular expression" with 20 threads (turbo off). The latency and throughput results look good too. With the GIL enabled (3.11), the compute intensive background task increases latency and dramatically decreases throughput. With the GIL disabled, latency remains low and throughput high. Here are the full results for 20 threads without the GIL: https://gist.github.com/colesbury/8479ee0246558fa1ab0f49e4c01caeed (nogil, 20 threads) Here are the results for 4 threads (the default) for comparison with upstream: https://gist.github.com/colesbury/8479ee0246558fa1ab0f49e4c01caeed (nogil, 4 threads) https://gist.github.com/colesbury/c0b89f82e51779670265fb7c7cd37114 (3.11/b108db63e0, 4 threads)
