Find and document opportunities to improve the response time of periscope

Use findings from MGNLPER-165 if applicable. 

Open followup tickets after discovery is being done.

We want to spend 5 days max investigating this please  

Things to consider:

• Caching results per user (we need to be aware of some customers with huge user-base)
• Pagination -> limit the supplier results in query vs in findbar.
  • Smart Search Suppliers, e.g: findbar shows 100 results, if the first search supplier returns 95 results, the second one should have a limit of 5 being applied.
• Do we iterate over all nodes?
• UI framework limitation (multiple queries being executed due to vaadin and UI framework architecture)
• consider restructuring of the periscope if it will make life more easier to implement the followup tickets
