Documentation Theme Page Left Hand Navigation Tree Slow Loading

[kmiklas]

Hello all,

We are using the documentation theme, with a page tree on the left hand side. This left-hand navigation is loading very slowly, more than 10 seconds.

We've been told that it's because of a relatively high number of pages, and that pruning out old pages will help. Another option is moving old stuff to a new space, but both of these options are time consuming.

Do you have any recommendations regarding how we could speed up the load of the navigation tree?

Also, is there an easy way to mark pages obsolete?

An inpection of the network tab in Chrome Inspector points to the following as the culprit

naturalchildren.action

/confluence/plugins/pagetree

tyvm!

We have something similar but different. Expanding the page tree in the Documentation theme for some users is slow and other users faster. The same behavior is in both IE8 and Firefox19. I can be on the same workstation with different users login in and out of confluence and the slowness is noticeabley slower for some users (sometimes fails to expand after 5 minutes) and for others users that same exact treewill expand in 2 seconds. Any ideas what might be causing this?

If you use permissions at the page level, then Confluence has to authorize each page as it builds the tree (users that don't have permission to see a page will not even see it in the page tree). Try comparing the users to see if they have different sets of permissions to see if that's the culprit.

Thanks for your responses. Would you kindly refer me to any link(s) with techniques to tune the cache and/or database?

What database are you using?

as to cache, follow Atlassian's guide: https://confluence.atlassian.com/display/DOC/Cache+Performance+Tuning

I think it would be caused by the amount of children pages. Confluence will check the permission of each pages therefore it would take time to load if there are a lot of pages in the page tree. As Harry said, I would suggest to do some database and caches tuning would help.

Hi, yes unfortunately that's going to be the case. Ways to speed up the process would be to increase caching within Confluence (if your cache is full) and/or adjust the time that this cache stays in memory.

Database tuning might also help.
