System Response
If the buffering flag is marked, all data required for conditionanalysis is buffered.
As a result, the performance for large amounts of data is improved.This means that enough storage must be available in the system memory.Otherwise, you have to use the hard disk. Advantages in performance arelost this way.
When data is not buffered, performance is worse with large amounts ofdata.

Procedure
Buffering is not required for small systems with little storage andwith few materials.
For large systems with sufficient system memory and many materials,buffering is recommended for reasons of performance.
If the program terminates in online mode because of a timeout,
you should run it in the background.
