TCP throughput and QUIC performance improved noticeably compared to Linux 7.1, while UDP remained unchanged. Sockperf also showed lower latency. A likely explanation is a change in fs/select.c switching the poll implementation from free_page() to the kmalloc() API, which improves scalability. The stress-ng micro-benchmarks confirmed poll performance is several times faster in Linux 7.2. Notably, CPU power consumption on the EPYC 8635P was slightly lower despite the performance gains. These improvements are not AMD-specific and should benefit other hardware as well. ## Full article daily.dev links to this article rather than hosting it.
