Hello,
FFCore 6.1.2 with AP, AA and OM.
We have quite large PDF-VT VDP jobs with 2 duplex pages per record, that we want to impose 18 pages per sheet.
We decided to design a workflow with:
- an initial Split component (Split by: Segments, Divide into Fixed Page Segments, Number of pages 36, Maintain Sub Job Order)
- another Split component (Split by: Pages, 2 branch conditions: All Pages Odd + All Pages Even)
- an Imposition component per each of the above Branch Conditions (Page Order: Sequential)
- a Join component, to gather the result of the Odd and Even impositions
- a Save component
The output file looks as we expected:
- first sheet with the 18 first "front pages" imposed
- second sheet with the 18 first "back pages" imposed
- third sheet with the next 18 "front pages" imposed
- etc.
However, we noticed that the processing time gets worse, depending on the number of records we process:
- 500 records (1000 pages) ==> 56 sheets: 00h01'03", i.e. about 8 records per second
- 1000 records (2000 pages) ==> 112 sheets: 00h02'41", i.e. about 6 records per second
- 2000 records (4000 pages) ==> 224 sheets: 00h09'36", i.e. 3.5 records per second
- 3000 records (6000 pages) ==> 334 sheets: 00h22'32", i.e. 2.2 records per second
Is this a known behavior?
Is there another option, to efficiently impose such large, duplex VDP?
Thanks!
AD
