[poppler] display page slice very slow

[Fabio Parodi (Technoleader srl)]

Thanks William for answering

Yes it is a 532MHz ARM11.

One example document is this one:
https://dl.dropboxusercontent.com/u/9451086/2-DESCR_648853%20IT-EN-DE_MANITO
U_RIGENERATO.pdf

The rendering time is very long for pages with pictures (10 to 20 seconds
depending on resolution and slice).

The source document is in ms-word format, and it is converted to pdf by
ms-word. We tried reducing the resolution of the images and the pdf gets
smaller, but the rendering time is about the same.

I will try to build poppler with profiling.

Thanks and regards

Fabio

Is the imx.35 based on a 532 MHz ARM 11 processor?  It might be around 30X
slower than just one core of a current i7 cpu, so 20 sec per page might not
be unreasonable for a complicated page.

Can you post a sample page?  Can you build poppler with profiling?  What is
the output device and resolution?  If your processor has multiple cores, did
configure enable multithreading in config.h?

Hello

 

I am new to this list.

 

We have an application running on a freescale imx.35 processor with embedded
linux.

poppler is very slow rendering pages with graphics, like 10 to 20 seconds
for a single page.

Is there anything we can do to improve the speed of render? 

 

Thanks and regards
