Post-rollback pprof on BenchmarkCollectNodesSparseWrite revealed collectNodes' per-descent leftPath/rightPath make+copy as 13% of alloc_objects (~26 allocs/op). Replace with append/truncate on a shared buffer pre-sized by Commit; flushfn consumers (NodeSet.AddNode, tracer.Get) already clone via string(path), so in-place reuse is safe. Benchmark delta (M4 Pro, go1.24.0, --count=5 --benchtime=5s): before: 9506 ns/op 15245 B/op 132 allocs/op after: 9095 ns/op 15008 B/op 106 allocs/op vs upstream/master@53ff723cc: allocs/op now -20.9% (was -1.5%). |
