Created attachment 66668 [details]
The attached document takes a very long time to load--over a minute on my system. When scrolling up and down LO regularly freezes while trying to draw the pages.
reproducible with LO 188.8.131.52 (Win7 Home, 64bit)
Opening the same file with MS Office 2007 takes only approx. 1 - 3 seconds.
In addition, there are a few smaller layout issues, but the checkboxes in the forms show errors. Maybe these checkboxes are also the reason causing this long load time?
Just a rough investigation:
Throughout the document, there are 256 calls to https://secure.dcsf.gov.uk/ for retrieving the images hosted on the domain.
Removing those images will help decreasing the load time of the doc to normal.
Indeed there are a lot of calls to secure.dcsf.gov.uk + certificates exchanges.
Since i know too little about certificates, I won't put any logs public.
Michael: I wonder if a certificate cache could be possible and help here. If useful, I can send you console logs.
Hmm; so another instance of terrible image management =) adding to the tracker.

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.
There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.
If you have time, please do the following:
*Test to see if the bug is still present on a currently supported version of LibreOffice (4.4.1 or later)
*If the bug is present, please leave a comment that includes the version of LibreOffice and your operating system, and any changes you see in the bug behavior
*If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a short comment that includes your version of LibreOffice and Operating System
Please DO NOT
*Update the version field
*Reply via email (please reply directly on the bug tracker)
*Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not appropriate in this case)
If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3)
2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to "inherited from OOo";
4b. If the bug was not present in 3.3 - add "regression" to keyword

I have retested with 4.3.3 and 4.4.2-rc2. In both versions the document takes a long time to import. Once imported performance is fine.
Confirmed it takes a long time to load, adjusted title and severity.
Win 7 Pro 64-bit Version: 184.108.40.206.alpha1+

Locale: fi-FI (fi_FI)
Testing in a Linux LO master log build, file affecting the load time is:
'Server certificate verification failed: issuer is not trusted'
Trying to open the graphic file with a browser, Firefox displayed this:
'secure.dcsf.gov.uk uses an invalid security certificate. The certificate expired on 02/05/2013 12:59 AM. The current time is 03/11/2016 11:31 AM.'
Dates are in en-US format.
When the bug was reported the certificate was valid, but now it's no longer possible to reproduce the exact bug cause.
