28462	ModelAdmin.list_editable unusably slow and memory intensive with large datasets	Ben Cole	nobody	"Since 1.10 `list_editable` on `ModelAdmin` is unusable for Models with a large-ish dataset.

The problem is caused by a recent change to how the FormSet is generated for the admin. Previously it was generated from the ChangeList result list, but it has been changed to use the admin's `get_queryset` which will return more than the current ""pageful"" of results (potentially the entire dataset) causing Django to generate a form for each instance. This results in Django consuming all available RAM and in some cases the python instance crashing. My personal laptop became unresponsive and I had to force power off.
