3084264 - Loading XML files into ASE needs to be optimized. Time increases exponentially with size.

Symptom

  • Reading external XML file and loading it into ASE can be improved regarding performance. With the increasing number of loading rows, the load time does not increase proportionally, but rather exponentially.
  • For example, we have XML file which contains 44784 rows. The time of loading data from it to ASE ? 180 sec. About half of it load during 36 sec, but 14% of it load during 2 sec.
  • Please see following table for details % of complete XML file

Number of loading rows Loading time, sec

14% 6400 2

29% 12775 10

48% 21643 36

74% 33361 96

100% 44784 180

  • So, with the increasing number of loading rows, the load time increases greatly.
