how many placemarker ?

How many placemarker are possible ? unlimited?

There is no any limit for markers
In last release I did ajax loading placemarks and paths, therefore page size can be very small

thanks for your feedback Dima.
Than should be also 5000 placemarks also not a problem ?

For latest version I included ajax loading map objects. Therefore it will load, and page size will not be too big

I'm trying to upload 17,000 placemarks and it causes the map to crash. I attached the .csv file to see if you can reproduce it on a test site, Dima?

I added it as .txt file because I see we can't attach a .csv file

Thanks you

Hi.
Here my map with your data, probably some duplicates (I didn't wait for end of loading and call it again).
And as a result I have 20240 placemarks.

You have to set some features for map.
First of all, dynamic loading map map objects
Go to map details, Advanced options tab
Set
* Loading map objects dynamically = jQuery
* Load type = All (for example)
* Buffer size for placemark = 100 (for example)

And enable clusterer
Go to map details, Placemarks tab
Set
* Show placemarks in cluster = Yes
* Marker cluster Zoom Level = 12 (example)

I marked "example" because you can do more fine turning

Buffer size give a count of placemarks with one ajax request to server

As result
test.zhuk.cc/index.php/zhosmmap-main/om-...placemark-list-table
it is temporary page with map on my test server. I leave it for a while
