Expand description

Per-tier timing breakdown for a single YPIR query, measuring each stage of the client-server round trip.

Fields§

§gen_ms: f64

Client-side YPIR query generation time.

§upload_bytes: usize

Size of the uploaded query payload.

§upload_q_bytes: usize

Bytes of the uploaded query attributable to the SimplePIR query vector itself (q.0 / pqr — the first arg to pir_types::serialize_ypir_query).

§upload_pp_bytes: usize

Bytes of the uploaded query attributable to pack_pub_params (the second arg to pir_types::serialize_ypir_query). Identical across queries that share a YPIR client_seed.

§download_bytes: usize

Size of the downloaded encrypted response.

§rtt_ms: f64

Wall-clock round-trip time (upload + server compute + download).

§decode_ms: f64

Client-side YPIR response decryption time.

§server_req_id: Option<u64>

Server-assigned request ID (from response header).

§server_total_ms: Option<f64>

Server-reported total processing time.

§server_validate_ms: Option<f64>

Server-reported query validation time.

§server_decode_copy_ms: Option<f64>

Server-reported decode+copy time.

§server_compute_ms: Option<f64>

Server-reported YPIR online computation time.

§net_queue_ms: Option<f64>

Estimated network + queue latency (RTT minus server time).

§upload_to_server_ms: Option<f64>

Estimated upload-to-server latency.

§download_from_server_ms: f64

Estimated download-from-server latency.
