Performance Problems: Map Unresponsive/Slow when panning or zooming & 200-300 markers

[matthiasprieth]

Hi, I tried to migrate from google-map-react/google-map-react to this library because of the jumping markers problem in the original library: google-map-react/google-map-react#1143

I was really happy first, but then the performance was a deal breaker when panning/dragging & zooming.
First of all I know I can use clustering with this library, but right now we try not to use it.
The strange thing is that I'm seeing such a better performance with the original library. Do you have any idea why that happens? As soon as we get rid of the markers, performance is no deal anymore. As marker components we just use simple divs without any images or something special.

So right now we'd rather stay with the jumping then the performance problems. I also want to say that on Firefox the performance problem is less of a deal (on chrome currently). Let me know If you've experienced something like that or if I should create a bug report.

Hi @matthiasprieth, I use the same code of this repository in our clients website. Someone has over 3k stores to show and performance is not a problem. We do use clustering though (and we used them also in google-map-react/google-map-react).
Soon I got time, I'll try to create a live version with more stores to see if I can find anything, or PR are welcome if you want to try.

Hi @giorgiabosello, have you had a chance to take a look on your end with a lot of stores?

[giorgiabosello]

@matthiasprieth not yet, sorry. It has been a very hard period. Winter holidays are coming, I'll take a look in a few weeks.
Thank you for your patience 🙏🏼

Hi @matthiasprieth I'm looking into it and I can confirm the issue about performances. Hope to find something soon.
