Does the Agora Signaling SDK have a limit on the number of concurrent online users and the frequency of sending channel messages?

The Agora Signaling 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 channelNumber 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.
