Slow popup (Feature Info) and selectFeaturesByIds JavaScript function

MichaelGinzburg

Hello, I experience following problem: the popup (Feature Info) is working very slow even when only one layer is on.

This is stock and unmodified widget.

Profiling shows that the JS function selectFeaturesByIds takes about 800ms.

Why does this happen? How can I improve the performance?

Thanks!

Try to put only one layer in webmap, it is improve the performance?
