- Linux 7.2 kernel to include performance improvement for anon_pipe_write, boosting speed of anonymous/unnamed pipes in shell pipelines and standard streams.
- Optimization by Breno Leitao of Meta resolves pipe to mutex contention by pre-allocating up to 8 pages outside the lock, reducing critical section stalls.
- Improvements show throughput gains of 6-28% and latency drops of 5-22% under normal conditions, with even better results under memory pressure (21-48% throughput, 17-33% latency drop).
