It’s taking too long to join a session

Video SDK Web
1

We have noticed that it takes around 5–6 seconds to join a Zoom session after clicking the Join button.

Is there a solution to reduce this time?

We are using Video SDK v2.1.5.

Thanks.

Hey @Moon

Thanks for your feedback.

Could you share the HAR file with us for troubleshooting, if possible?

Thanks

Hi @vic.yang
I cannot share the full HAR file with you. Which specific part do you need? I can send you that information. Also, how many seconds is considered normal for a user to join a session?

Hi @Moon

HAR files provide a clear view of the network timing for joining a session. Under good network conditions, joining a session typically takes around 2 seconds.

Could you share the session IDs where the join session time was unusually long, if possible?

Thanks

Hi @vic.yang
I tried to join a session and it took about 4 seconds

The time it takes to join a session depends on the network conditions. In this session, it took a total of 3.3 seconds, including:

  • 0.4 seconds to fetch session information (including available clusters)
  • 1.2 seconds to identify the nearest and fastest cluster node
  • 1.7 seconds to connect to the media server

We have also been continuously optimizing the session join speed.

Thanks

Hi @vic.yang
We primarily focus on the Singapore market. Could it support a dedicated cluster node and server?
If so, would that help reduce session join time?

Hi @vic.yang If possible, could you help me craft a response to the question above?

Hi @Moon

Could it support a dedicated cluster node and server?

We have already deployed data centers in Singapore. If users are located in Singapore, they will be able to connect to these data centers.

Thanks

Hi @vic.yang,

Thanks for the information.

Since most of our users are in Singapore and you’ve confirmed that data centers are already deployed there, we’d like to ask:

  • Is there a way to configure the system to always use the Singapore cluster/server by default for our sessions?
  • If so, would that help reduce the 1.2s used for identifying the fastest cluster and the 1.7s for media server connection?

We’re looking to further optimize session join time as much as possible.

Appreciate your help!

Hi @Moon

Thanks for sharing the information with us.

  • Is there a way to configure the system to always use the Singapore cluster/server by default for our sessions?

Yes. You can specify your preferred data centers using the geo_regions field in the JWT.

  • If so, would that help reduce the 1.2s used for identifying the fastest cluster and the 1.7s for media server connection?

It depends on the user’s network conditions — theoretically, it can be improved.

Thanks
Vic
