Real-world performance data from notifications sent through Knock
| Message volume | Growth | Status page updates (30d) | Status page updates (90d) |
|---|---|---|---|
1M–10M | 5th of 5 ↑ | 6 | 16 |
From March 3rd to June 1st, Knock routed 1M–10M messages through OneSignal.

Response time
Response time measures how long OneSignal takes to accept a push API request from Knock, including connection overhead and any automatic retries. Lower values mean faster notification hand-off.
| Median (p50) | p90 | p95 | p99 |
|---|---|---|---|
219ms | 320ms | 389ms | 687ms |
From March 3rd to June 1st, OneSignal averaged a daily median response time (p50) of 219ms across all days in the range, meaning half of all push API requests on a typical day complete in under 219ms. The 99th percentile averaged 687ms, with a peak daily p99 of 15150ms. This is slightly higher than some providers, which may reflect additional processing OneSignal performs on notification acceptance.
Error rate
Error rate tracks the ratio of 5xx responses and timeouts to total push API requests. Knock automatically retries failed requests, so transient provider errors rarely affect end-user delivery.
| Avg. daily error rate | Highest daily rate | Peak error date | Zero-error days | Days above 0.01% |
|---|---|---|---|---|
0.10% | 2.88% | Apr 13 | 77 | 8 |
From March 3rd to June 1st, OneSignal averaged a 0.10% daily error rate for 5xx responses and timeouts, with the highest single-day error rate reaching 2.88%. This falls within the normal range we observe across push notification providers on the Knock platform, reflecting generally reliable service. Knock automatically retries failed requests, so transient provider errors rarely affect end-user delivery.
About these metrics: Data represents notifications sent through Knock to OneSignal during the specified period. Response time measures time from Knock to provider acceptance. Error rate includes only provider 5xx responses and timeouts.
