Performance Issues and Site Freezes when Trails are Rendering

[St0rml]

Hey, I really enjoy Wanderer, thank you for your hard work!

Summary

At the moment, I have bad performance issues on the overview map. The map itself renders responsively, however, when I look at an area with trails in it (I have 22 total at the moment), I sometimes have to wait ~ 10s for the browser to render all the tracks and react to my inputs again. Then after every move on the map, when trails are visible, it freezes for a few seconds and so on.
I don't have a high-end PC, but at the moment Wanderer is the only website, where I really notice performance issue, hence I suspect it might an issue.

About the tracks

I noticed in another software, that my tracks for a 30km bike recording contain approx. 7500 Points. I don't know if that is normal or not though...

I can confirm, there are several performance issues. I'm running wanderer on a Synology NAS.
But I can't reproduce on my dev workstation.

The main problem seems, that always the whole database will be retrieved...
Sample: I had a long loading time, when press 'New Trail' until the page was loaded. After deleting my trail 'List', the loading time has been increased massively. First code review proves that: the whole list including all containing trails will be loaded when creating a new trail.
When opening the trail overview page, all trails will be loaded completely.

Maybe, there can be made some improvements.

Many thanks.
