Graphite performance telemetry
Benchmark Observatory
A fresh absolute latency snapshot of the Rust engine (graphite serve over the 64-graph fixture corpus) for the exact main commit, with paired PR regression evidence only when its base and candidate match this integration exactly.
Exact main commit
Fresh Rust engine snapshot
Cross-graph Cypher latency of the shipped graphite binary over fixture64: the declared suite includes string searches, sorting, aggregation, traversal, WITH, ID and schema queries. Requests run sequentially; the first pass mixes first-use and already-warm state. Score is the median pass; the interval is the min–max spread. The aggregate rows describe percentiles across different cases, not server request p50/p95. History comparisons require matching query and suite identities. Absolute scores and cross-run deltas are informational on hosted runners. Paired blocking decisions live in the evidence section.
