Affects Version/s: 5.2.9 EE, 6.1.0 CE RC1
If editing a wiki page images can be pasted directly to the editor (Ctrl+V) and the images is saved encoded in base64:
<img alt="" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAsIAAA........
When requesing an RSS feed, this feed shows the differences among the wiki versions. If the change is in the same line (for example changing a pasted image for a different one) it takes many hours even days to compute it.
STEPS TO REPRODUCE
1.- Add a Wiki portlet
2.- Add a page
3.- Paste an image
4.- Edit again the same page
5.- Delete the previous image and paste a different one
6.- Open the Details link of the Wiki page
7.- Open the RSS link, it is like: http://localhost:8080/c/wiki/rss?p_l_id=10181&companyId=10152&nodeId=10450&title=page
The RSS feed takes very long time to appear (hours)
It should be displayed immediately (seconds)
