Hey,

I have several multinode tree pickers (Umbraco.MultiNodeTreePicker2) that we use to pick taxonomy for article pages. I'm seeing some painful performance when a lot of nodes are picked.

Here is the code (using Models Builder):

            var s = new Stopwatch();
            s.Start();


            var tmp = CurrentPage.GetPropertyValue<IEnumerable<IPublishedContent>>("countries").ToArray();
            LogHelper.Info<GoogleTagManagerController>($"Countries: {s.ElapsedTicks}t {s.ElapsedMilliseconds}ms");

            var tmp2 = CurrentPage.GetPropertyValue<IEnumerable<IPublishedContent>>("focusAreas").ToArray();
            LogHelper.Info<GoogleTagManagerController>($"Focus Areas: {s.ElapsedTicks}t {s.ElapsedMilliseconds}ms");

            var tmp3 = CurrentPage.GetPropertyValue<IEnumerable<IPublishedContent>>("services").ToArray();
            LogHelper.Info<GoogleTagManagerController>($"Services: {s.ElapsedTicks}t {s.ElapsedMilliseconds}ms");

This is what I'm seeing in the log:

Countries: 53152t 20ms (1 node picked)
Focus Areas: 54037t 21ms (0 nodes picked)
Services: 2198790t 868ms (43 nodes picked)

Does anyone have any ideas why it might take three quarters of a second to fetch 43 pages from a picker?

Cheers Chris
