Bug report #21579
layers with same name will make system slow to an unusable level
|Affected QGIS version:||3.6.0||Regression?:||No|
|Operating System:||Win 10||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||not reproducable|

If I mistakenly add 2 layers to the layer panel e.g. each named "IPT_SouthShore_unique", system slows to a crawl. Each layer points to the same shapefile. When I remove one of the layers, system runs fast again.
Id there is no underlying bug e.g. natural contention is occurring, then an enhancement to add new layer could check for existence of layer with same name, possibly warn user and give option to proceed or not.
