Hello Pano friends, what can I do to improve the loading speed of my tour. It currently takes almost 25 seconds for the first panorama to appear.
For example, can I have the audio files loaded after the panos or are there other ways to improve the speed.
Maybe there are also errors that slow down the loading.

Thanks for your help!

Actually I just wanted to ask if there is a way to only load the files needed for the start and only load files when they are needed, e.g. audio files.

I found these errors and don't know how to fix them. I also checked every single node to see if there was an audio file that wanted to start the music automatically, but found nothing. Can someone give me a tip?

It was a while I was present on this forum... I spend few days solving the problem of crashing the btowser with my audio files, which were in a correct mp3 format so I foud your post with no reply in almost half a year...

I didn't know there it is an audio file size limit when implementing it into p2vr project. I have implemented 3 hours of the ambient sound in mp3 file format for a long panoramic slideshow of about 300 panorams. I have checked the format, even tried diffrent bitrates to be the correct one - and it played fine within browsers (Edge, Chrome, Mozilla) on Windows (10, 11) , Linux Ubuntu 12 but with various Androids (Samsung prime smartpones and tablets) crashed after about 30 s and with iOS (iPad and iPadPro Max) it crashed immediately. I cut the length of the audio file to 10 min., and converted it to mp3 with the same compiler, and it worked ok.
Now I am digging into where was the real problem...

Just to add that I have broadband 1000 Mbit/s internet connection and the server is among fastest in EU (ARNES) so the loading speed shouldnt be a problem. I have connected my testing devices to 5G which is only 450 Mbit/s and the same resoult so the loading speed was not the issue.
