**Description**  
Hi there, we are using the websdk to connect a 1 on 1 Video and audio meeting between 2 users.  
I wanted to know if anyone here has any tips or tricks to speed up the load time of the web sdk?

From my testing I have found that it takes a 6-8 seconds for the ZoomMtg object to perform the two lines below and get to the following console output “\>\>\>\>\>\>\>\> CREATE JSMEDIASKD INSTANCE \<\<\<\<\<\<\<\<”

Can we remove them? if not read below…  
ZoomMtg.preLoadWasm();  
ZoomMtg.prepareJssdk();

As our app is going to be runnig for multiple different meetings I was thinking it would be good to cache the resources which are loaded by these 2 lines so they can be used over multiple meeting sessions. Although I am not sure how to…

Any thoughts/ ideas will help greatly 😄

**Which version?**  
websdk@1.7.7

Hey @james1,

Are you using the [CDN](https://marketplace.zoom.us/docs/sdk/native-sdks/web/getting-started/integrate#cdn) or [Local](https://www.npmjs.com/package/@zoomus/websdk) version of the Web SDK?

Thanks,  
Tommy

Hey @james1,

If using the Local version, the load times should be quick since you are hosting the files.

Can you try upgrading to version [1.7.8](https://www.npmjs.com/package/@zoomus/websdk) to see if that fixes the issue?

Thanks,  
Tommy

The latest guidance for best performance and speed is to use our CDN, which is the default behavior.

Follow the guidance here: [Meeting SDK - web - client view - Import](https://developers.zoom.us/docs/meeting-sdk/web/client-view/import/)
