The Agora RTM SDK does not have a limit on the number of concurrent online users. However, Agora has the following recommendations on the maximum number of channel messages per second for a single channel:
| Concurrent online users in a single channel | Number of channel messages per second |
|---|---|
| < 1,000 | < 200 |
| ≥ 1,000 and < 10,000 | < 100 |
| ≥ 10,000 | < 30 |
- If the number of messages per second exceeds the recommended values, latency can increase significantly and may also cause the following issues:
- The user cannot send or receive messages.
- The user always stays in the RECONNECTING state or keeps switching between the CONNECTED state and the RECONNECTING state. For other users, the current user may appear offline.
- Agora provides customized service to increase the number of messages per second without affecting latency or stability. Please contact support@agora.io for more information.
