NowConnect LDAP Performance Results (localhost:1389)

Date: 2025-08-18

Environment

  • target: localhost:1389 (mapped to NowConnect Cloud listener 389)
  • bind DN: cn=admin,dc=example,dc=org
  • base DN: dc=example,dc=org
  • SSL: false

Scenarios and results​

Baseline (10 workers × 2 RPS, 30s, page=100, filter (objectClass=inetOrgPerson))

  • requests_total: 610; errors_total: 0
  • latency (ms): avg 59.07; p50 49.19; p90 107.34; p99 152.82; max 191.13

Run A (moderate load: 20 workers × 3 RPS, 30s, page=100)

  • file: perf_nowconnect_runA.json
  • requests_total: 1615; errors_total: 0
  • latency (ms): avg 368.56; p50 370.79; p90 456.14; p99 623.32; max 788.32

Run B (high concurrency: 50 workers × 2 RPS, 30s, page=100)

  • file: perf_nowconnect_runB.json
  • requests_total: 1495; errors_total: 0
  • latency (ms): avg 1011.40; p50 1028.19; p90 1601.24; p99 2089.19; max 3447.43

Run C (large-page search: 10 workers × 2 RPS, 30s, page=1000, filter (objectClass=*), attrs uid,cn,sn,mail)

  • file: perf_nowconnect_runC.json
  • requests_total: 610; errors_total: 0
  • latency (ms): avg 136.45; p50 125.41; p90 225.83; p99 295.51; max 338.58

Observations​

  • Stability: No errors across all runs; tunnel and premise behaved reliably.
  • Latency scaling: Sub-200ms p99 at baseline; degrades under heavier parallelism (p99 ~0.62s for Run A and ~2.09s for Run B), consistent with upstream LDAP and tunnel backpressure.
  • Payload size: Larger page size (Run C) increased latency vs baseline but still kept p99 < 300ms under modest load.

Suggested SLOs and gates​

  • CI perf gate (baseline scenario): fail if errors_total > 0 or p99_ms > 200.
  • Soak/high-concurrency: track trend; raise alert if p99_ms regresses >20% from prior.
