Hey @guiltdriver,

Are you using the China CDN?

Thanks,
Tommy

Hey @tommy,

We copy all JS and CSS files in the CDN links to local project.
We found that the reason why the network is slow is to load three wasm file below:

My ip address: 124.65.225.138

Hey @guiltdriver,

Have you provided the China CDN for the wasm files?

// In China use jssdk.zoomus.cn:
ZoomMtg.setZoomJSLib('https://jssdk.zoomus.cn/1.8.0/lib', '/av');

Thanks,
Tommy

@tommy Tkx! But the users of our website are from all over the world, not just in China, is there a more general solution?

Hey @guiltdriver,

Are you able to detect where they are located and supply the respective CDN? If not, please use the Global CDN.

Thanks,
Tommy
