Experience Builder measuring tool performance

[Maryse]

Some users have reported issues with the Experience Builder measuring tool since the recent update - both the default measuring tool, accessible from the map settings and the measuring tool widget.

It's quite slow to use, freeze often and randomly crash the whole Experience Builder (it was working fine before that).

Is it a known issue ?

Hi @emwing ,

Really appreciate for sharing the application. But as I tried, it looks good no obvious performance issue is found.  Do you mind sharing a screenshot video or GIF demonstrating what you are seeing? Appreciated! 

[WeiYing1]

Just want to confirm are you seeing the performance issue in the Measurement widget loading or when during measuring? 

[Maryse]

@WeiYing1  The performance issue is when measuring distance and area.

I haven't had time to re-create a WebApp for public sharing, but the issue seems to resolve, when drastically reducing the number of layers available (as mentioned by @emwing).

@Maryse Thanks for the update! I have tried the same scenario again by adding many layers but I didn't see significant performance issue.
Would you do me a favor to try two things:
1. For the previous map with which you seeing measuring performance issue in ExB, could you try open it in Map viewer and use the Measurement tools there see is same performance problem occurs? 

2. While you are seeing the issue, you you try measuring while holding "CTRL" key? With that how the performance looks (Because snapping is enabled by default for measuring, holding the CRTL key can temporarily disable it. We are guessing the snapping with many layers may have problem.)

Thanks,
Wei

@WeiYing1  Thank you, please see my answers below:

1. The performance issue is the same in Map Viewer

2. Holding CTRL helps with "plotting" points to measures a distance or an area, but the overall issue is the same : the widget is slow and potentially crash from the moment it's open

(e.g. Just now, I measured a distance holding CTRL, then tried to measure an area, which crashed the whole ExB)

Thanks

I am experiencing this as well. As soon as any of the users use the measurement tool, the app slows down exceptionally. Users have to refresh after using to be able to use the app. One user had the app crash completely.

@WeiYing1 My map has about 50 layers on it, so it's pretty memory intensive. I can't share my app easily, but happy to hop on a call to show you what we are seeing.

This has been a significant issue for me as well. My webmap essentially becomes unusable after using the measuring tool. The only way to solve this has been to refresh the page.
