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

[Lucas Peng <lucasp0927@gmail.com>]

Thanks for your prompt response,

1. I get "Org-mode version 6.35i" with M-x org-version.

2. I am exporting my personal wiki page with latex math to HTML.

3. It took me 28 seconds to export the file Nick metioned with 6.35i.
    But only 5 seconds with 6.34c.

    BTW I am using Ubuntu 10.04 beta2 and emacs23.

Thanks,
Lucas
