I used Angular-style to create a TreeList.
In my initial test, the tree only have 3 level, root level with 1 node, second-level with 30 nodes, third-level with 1 or 2 nodes. Total are ~60 nodes.
I checked another thread mentioned that defining column template will have performance penalty and I already fixed all and it works fine on Chrome (Version 50.0.2661.102 m)
But when I use Firefox (46.0.1), it is very slow. Loading the tree is already slower than Chrome. Especially, when expand / collapse the node, it takes 3-4 seconds (while Chrome only take less than a second).
I already disabled all Plugins on Firefox.
Please advise any way I can improve the performance.
