HTTP2 CUTS OVERHEAD 30 PERCENT ACROSS HOT PATH

Node core just shipped a series of performance wins that strip per-request allocations from HTTP2, skipping unnecessary trailers round trips and eliminating object clones on every respond() call.

Three surgical http2 optimizations landed overnight that compound into meaningful throughput gains [1] [2] [3]. The first kills redundant EventEmitter tracking on stream listeners by overriding methods directly instead of subscribing to newListener events. The second eliminates a wasted DATA frame and C++ callback on every response that never registers trailers, which is most of them. The third removes object cloning from respond() and consolidates header lookups into a single pass. Together these cut hot-path allocations without touching the API surface. On the test_runner front, you're now getting entryFile reported in TestStream events [4], closing a gap for test harness integrations that need to trace which file kicked off a given test. A reliability fix landed that prevents worker stack size tests from flaking under tier-up churn [5]. On the website desk, the Undici docs are back to the stock Node logo [6] [7].

Action items

→ Benchmark your http2 server against the latest build - these changes compound on sustained load nodejs/node [plan]
→ Update test harness integrations to consume entryFile from TestStream events nodejs/node [plan]
