Hi there,

From what I heard about leaflet is that it (more precise: the browser) limits the number of parallel connections to further URLs to a defined threshold value. Therefore a mapping framweork such as LEAFLET can only consume a number of tiles at the same time in parallel. In times of "full display mapping" a frontend requires 50-100 tiles and I'd like to speed up the rendering process.

Imagine we have a backend xMapServer (cluster) with sufficient number of backend modules:
Does it make sense to add further logical names to perform a "detour"? This approach could reduce rendering time by a factor 3 Any experience in the crowd?

Best regards,
Bernd

IMO the difference running xMap with 1 modules vs 2 modules is noticeable in the end user experience. However if you would upscale to 4 modules and thus 2 logical names for the host I find the difference becomes less noticeable. Even if the xServer is not in the local intranet (for example you are using xServer internet) most sites I visit often have a good enough internet connection that it doesn't make a noticeable difference.

My common advise is to start without multiple logical names and later you can always add this to your code if users still find the map sluggish.
