RTF test case

With a simple RTF document (attached) it takes around 3-6 seconds to generate a corresponding PDF.

This is a single-page document; if I create a multi-page document, which is structurally similar to this one, the time increases linearly up to about 500 pages; I haven't tested beyond that point.

This makes the conversion of any non-trivial documents logistically impractical with LibreOffice.

I can do it instantly in 1 sec with your attached file (LO 4.0.6.2, Win7 32bit).

Please inform your OS. Also try again with LO 4.1.3.2 & resetting user profile.
Comment 2 Kai 2013-11-01 18:27:20 UTC
Did you actually time it on the command line? If so, can you say exactly how long it took?

Also, even 1 second per page is ridiculously slow.

please name your O/S

on my LibO 4.1.3.2 under Win7 64bit it takes 1 or 2 seconds to export as PDF.
not 3 to 6 like you reported
Comment 4 Kai 2013-11-17 01:04:40 UTC
Ubuntu 12.10; further testing shows that the *first* conversion of the single-page doc takes 3-6 seconds (according to time, using CLI conversion); subsequent conversions take 1-2 seconds and larger documents amortize to that time per-page as well.

Still, 1-2 seconds per page is insane.

try uploading a 10 pages document so we can effectively see if it takes 20 seconds to save on Windows.

18 pages testcase

@Kai
I created an 18 pages RTF file duplicating you original one.
It takes just 4 seconds to export the whole file to PDF with LibO 4.1.3.2 under Win7 64 bit. do you experience different exporting time?

I change platform from ALL to LINUX
I change status from UNCONFIRMED to NEEDINFO
