Context (required)

My big problem is the same as this user of the community:

I can not introduce my site to anyone because afraid of the speed performance of my web after publishing to subdomain.flutterflow.app (or main custom domain), while it is working and scrolling smoothly on FF default run mode.

Hi Victoria,
I think this is to validate by the FF Team

@Franco98404 Thanks for reporting the issue. Can you add a run mode link and a published link for the project where you experience the issue?

[Franco98404]

Yes, here are the links.

https://app.flutterflow.io/run/Kd6tvLMXa1vPM7yimdv1

Probably you need the credentials to enter the app, in this case, where can I share the credentials privately?

[aemelyanovff]

It would be very helpful if you could create another project that does not require auth, ideally with only one page :-) I'm reluctant to troubleshoot a big existing project I know nothing about.

I don't see significant difference in scrolling performance between web publishing and run mode in my projects.

Especially on Android the web page run so slow, I have and good smartphone but the experience is very laggy. Instead, the native app works smoothly.

[aemelyanovff]

Thanks for the info!

Both links are about equally laggy on my machine actually... And the reason they are laggy is that you load 50 images over the network, each image is about 1MB. This will be slow, especially if the internet connection is not great. Once images are loaded, everything scrolls pretty fast.

One thing you can do is set width and height for the random image. Then image sizes transferred over the network will be much smaller, and everything will load much faster.

[Franco98404]

@aemelyanovff What about Android? After the images are loaded, they are still laggy.

Thanks for your advice, I will apply it!

[aemelyanovff]

Native apps will always run much faster than web apps. I don't have an Android device to verify - I can only try in an emulator and it's pretty much always laggy - but I don't see evidence that web publish to subdomains runs noticeably slower than run mode, so I'm closing this ticket.

My best advice here is to reduce the size and/or the number of images on the page, then it should be faster.
