Re: Bug: create latex png while export to HTML become very slow [6.35i]

[Carsten Dominik <carsten.dominik@gmail.com>]

Hi Lucas,

thanks to some detective work by Ulf Stegemann and Nick Dokos we have  
now identified what was causing this slowdown.  The new LaTeX setup in  
6.35 led to the inclusion of more packages into the image generator.   
The worst offender was hyperref.

In the latest git head, this problem has been removed by adding  
switches to the settings in org-export-latex-default-packages-alist  
and org-export-latex-packages-alist, as to whether the package needs  
to be included for snippet image creation.

If you get the git version, or wait for 6.36 which will be release  
this weekend, HTML export of your files should basically happen at the  
old speeds again.

Thank you for your report, and thanks to everyone who helped resolving  
the issue.

- Carsten
