fastest way to put 6millions items in a treetable

Ok i have a clean json object [ { id:1, label : “mylabel”, data:[…] ] so it’s 6millions objects (and labels).
The fastest way to display this in a treetable (mytree.parse(myObject,“json”) is too slow).
Any idea ?

You can use dynamic loading. And load only part of data at once.
