System Load and Performance > System Load
  
System Load
System load comes in the following three dimensions:
• Item and resources
• Scheduling horizon days
• The number of MRP details; that is, production order records, component records (BOM), routing records, and so on

System Load
Load on the client and server increases as any of dimensions increase, impacting system response time and, hence, performance.
Search criteria and user preference settings impact the three dimensions, too, as shown in the following table, which presents the performance impact by order of impact.

Performance Impact by Order of Impact
 
Impact
(1=Highest)
Area
Impact
1
Search criteria
This is the most significant impact, affecting the number of item/resources and therefore, indirectly the number of production orders, components, and routings.
2
Scheduling horizon
The horizon affects the number of production orders, components, and routings. After search criteria, this is the most significant parameter that affects performance.
3
Other user preferences
Setting other user preferences can impact performance; see User Preferences Impact.
