@andreiem I added a random sleep time before all the procedures started. The 1st thread starts. and then 2nd thread .. 3 and 4 5 ... Since they do not do the same operations at the same time, they do not consume much processor.
@Adisame forgot about DM, use mongo compas or other mongo GUI to see on DB, export, import etc. Bas work good with mongo only on skript side, but not on data manager
