Confluence Performance issue - authenticated users take ~9s to render page, anonymous only 2s

Question

We are investigating performance issues with our server and have been unable to determine yet the cause. We've tried all the basic approaches we can think of:

▪increasing RAM

▪moving to physical hardware

▪moving the confluence-home directory local

The strange thing with the current space we are investigating is how much longer page renders for authenticated users take....about 9seconds from about 2seconds or +4.5X longer.

Has anyone seen this behavior with Confluence before? (where authenticated users take a LOT) longer?

The page does have a Zen-theme-brand, but no other content nor macros are on the page.

Any ideas how can we troubleshoot this?

thanks!

Hi Samuel,

Thanks for the great suggestions.

I think we traced this particular performance issue to the use of the Confluence DraftManager which seems to look through even "orphaned drafts" when invoked.  It just so happened this was only happening for authenticated users.

It was a slippery one but ultimately tied to a plugin's use of an underlying API that seems to not be optimized. Rewriting the plugin code invoking the API and deleting orphaned drafts seems to have solved this particular issue.

It was strange behavior I'd not seen so just thought I'd post to answers in hopes that someone had tripped across the same problem :)

thanks,

Brendan
