Hey @kamleshwithbang,

Thank you for reaching out to the Zoom Developer Forum. You’re correct in that the Zoom Desktop Client will provide the best performance. There is a known issue with high cpu usage on the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk).

Currently, the best workaround is to enable SIMD Support as outlined at the bottom of this article:

Let me know if that helps.

Thanks,  
Max
