performance-test of mail merge jobs in OOo
Regarding to my performance-Tests for issue #118222 (the corresponding diagram
is also attached to this issue) it is obvious to see that mail merge into one
file in OOo has a non linear timing behaviour regarding the number of processed
database elements (n). It seems that the OOo mail merge has a complexity of
O(n²).
Due to this behaviour the mail merge of large jobs into one file is in much
scenarious not practical. On my host the merge with over 500 datasets needs
more than acceptable time. We have got real scenarios where people need to
perform mail merge jobs with over 4000 datasets.
The improvement should be to get a nearly linear timing behaviour by optimizing
the current mail merge algorithms and underlying data structures.
