Performance in LNM

Summary:

Doubts in LNM performance and data

Content (required):

Hello. I'm performing the configuration and a series of tests in the LNM module and we're facing performance problems to run the models. For example, scenarios of changing the collection location or adding weight, even using only 2 order releases is taking about 2 hours for planning.
Would that be the proper behavior? Is there any performance setting, performance improvement that can be performed?
Also we saw that OTM don't have an specific OrderRelease table to be used. So, how we can do if is needed to add more orders to the LNM scenarios, as an increase of demand.
