Bug ID: 101310
Summary: PDF export time is quadratic in size of document
Product: LibreOffice
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Printing and PDF export
Assignee: [email protected]
Reporter: [email protected]
Exporting large documents to PDF is disproportionally slow. Something is taking
time quadratic in the size of the document:
$ python -c 'for i in xrange(50000): print "%06d" % i' > 50k.csv
$ python -c 'for i in xrange(100000): print "%06d" % i' > 100k.csv
$ python -c 'for i in xrange(150000): print "%06d" % i' > 150k.csv
$ python -c 'for i in xrange(200000): print "%06d" % i' > 200k.csv
$ python -c 'for i in xrange(250000): print "%06d" % i' > 250k.csv
$ time soffice --headless --convert-to pdf 50k.csv
convert /home/jeffrey/tmp/50k.csv -> /home/jeffrey/tmp/50k.pdf using filter :
calc_pdf_Export
real 0m7.732s
user 0m7.635s
sys 0m0.115s
$ time soffice --headless --convert-to pdf 100k.csv
