Test procedure: Open PdfBox Debugger, load PDF, capture render time from label in lower left corner of window.
With PdfBox 2.0.17 - this PDF renders in about 4.8 seconds (but is missing the colored pattern). With PdfBox 3 baseline (no code changes) - this PDF renders in 16.2 seconds seconds. With PdfBox 3 caching changes only (no BigBufferedImage) - this PDF renders in 14.7 seconds So I have not done any damage, and I've sped it up a little bit. But that's only with a single render. Because printing can involve rendering many times for banded printing (on my test device, I am seeing well over 100 bands when printing this sample file), the page level caching should be substantial (the rendering on your test PDF is so slow that it almost can't be printed) - it is certainly a huge improvement for my test document. So I think my improvements to the caching (both the tile cache and adding caching at the page level) are valid. - K Kevin Day *trumpet**p| *480.961.6003 x1002 *e| *ke...@trumpetinc.com www.trumpetinc.com <http://trumpetinc.com/> LinkedIn <https://www.linkedin.com/company/trumpet-inc.>| Trumpet Blog <http://trumpetinc.com/blog/>| Twitter <https://twitter.com/trumpetinc> Proud to be Great Place To Work <https://www.greatplacetowork.com/certified-company/7012667> certified since 2019 On Sun, Nov 7, 2021 at 8:34 PM Tilman Hausherr <thaush...@t-online.de> wrote: > Hi, > > I don't have much time right now, but please test your change with the > file from > > https://issues.apache.org/jira/browse/PDFBOX-3688 > > Tilman > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@pdfbox.apache.org > For additional commands, e-mail: users-h...@pdfbox.apache.org > >
