Internal links in a large PDF taking too long to open

[steveng38859182]

My problem is a PDF document that after I added some internal links, it takes too much time to go from page to page or from a link to corresponding page. I am using version 11 of Acrobat Pro on a windows 7 machine. The document is 123 pages and is 11 Meg in size. The document starts out with a list of places and page numbers and followed by a series of maps. The links are put over the page numbers in the list so the users will then go directly to the corresponding area on each map. There are 1621 places/links. It takes a minute and twenty seconds to open the PDF. To go manually from page to page takes twenty-eight seconds. To use the link to go to one of the locations takes twenty seconds. I have tried to save it as an “Optimized PDF” and a “Reduced Size PDF” and this didn’t make any difference. The problem does not get any better on any different machine. Everyone really loves the concept but wants to know if things could be speeded up. Any help with this would be great!

My guess is each page has a large number of individual graphics (and perhaps text) objects, which can take a lot of time to render. But it's really hard to say what's wrong without seeing a sample. Can you post one somewhere?

Here is a one of the list and one of the drawings.

I'd really need to take a look at an actual file. You can't tell much with just a screen shot.

You have some 100+ pages of CAD sourced PDF pages?

Page size? Actual PDF producer?

These and other variables can result in only marginally ISO 3200 (PDF ISO Standard) compliant PDFs and/or images of the engineering drawing rather than renderable text and lines and/or LARGE file size footprint and/or outlined fonts (a graphic drawing of the glyph rather than one rendered from something mapped from Unicode and so on.

Consequence is slow, slow pull up and screen render.

A hardware variable that contributes is what is used for graphics? Slow (nice 3-speed bicycle) is the integrated with mother board approach. Desired (the mountain bike) is a dedicated graphics card - more RAM is better (and this isn't that expensive these days).

Bentley / AutoCAD / other high end stuff Can output proper PDF (see user manual/Help) but if not properly set up even they can/do output subpar PDF. Low end stuff - well it is low end (gigo in operation).

How can I get you a copy of the file?

If you don't want to post one publicly (e.g., acrobat.com, dropbox), feel free to email me one at: acroscript at gmail dot com

AutoCAD 2016 was how the drawings were created. I used a "dwg to pdf.pc3" to convert to PDF's. 11" x 17" is the page size. My machine is running an Intel Core i3-2120 CPU @3.30GHz, 16.0GB RAM, NVIDIA Quadro K2000 video card.

The file that you sent took a similarly long time to load and load pages. It probably is due to the large number of vector objects on each page, but I can't rule out some other issue.

I also created a version without the links and it opens right up and you can go from page to page like you're supposed to. I just sent that to you George.

That's interesting. I'll be able to take a look at it later today.
