Uwe seems to be right here. Following his suggestion, I have tried to export the same document two or three times successively to PDF format, in order to separate the preparation (“Umbruch”: page breaking etc.) from the real PDF export. To make the comparison easier, I have used again my “big book sample” from comment #7. The results, given in the same table as in comment #7, but with current LibO versions and in minute/seconds format (easier to read): 3.5.7.1 3.5.7.1 3.6.2.2 3.6.2.2 1st pass 2nd/3rd pass 1st pass 2nd/3rd pass ========================================================================= Stage I 50s 3s 50s 3s (spinning cursor) ------------------------------------------------------------------------- Stage II 5s 2s 4m50s 5s (progress bar visible, but disabled) ------------------------------------------------------------------------- Stage III 1m50s 1m50s 1m54s 1m42s (progress bar showing progress) ========================================================================= Total 2m45s 1m55s 7m34s 1m50s So, while it is still true that the 1st pass of the PDF export is far slower in LibO 3.6.x than in 3.5.x, the 2nd and 3rd passes are equally fast in both versions -- I consider the difference of ca. 5 seconds as measuring error; maybe 3.6.2.2. is even a little bit faster, as Thomas has suggested in comment #8. Nice! Now it seams reasonable (the LibO documentation is bad here; a developer could tell us for sure) that stage I and II are related to the document preparation, i.e. inserting page breaks, maybe collecting font information etc., and that the acutal PDF export is identical with stage III. So what has become slower in LibO 3.6.x is very probably not the PDF export, but the formatting of the document. This _is_ a problem, of course, but a different one, which needs more testing (*); the current bug report, which assumed that the PDF export has become slower, can be closed now. Thank you all very much for your interest and testing! (*) If somebody else is interested in testing this document formatting time slowdown, we could collaborate in designing a nice test, executing it on several platforms and submitting a new bug report for that; just let me know if you are interested! -- You are receiving this mail because: You are the assignee for the bug.
