Confluence website page loading speed becomes slow, performance becomes slow?

What is the general cause？

[Hornbuckleson Senior]

Some pages in Confluence can be slow to load due to dynamic content or macros being used in it. This page identifies some of those scenarios. You shouldn't be following this guide if Confluence is slow overall and all pages experience slowness.

Content in body of the page can contribute to how slow or fast it loads. Especially some macros which are pulling data can make the rendering of the page slow. So, we will need to identify any such content. Most common ones are

Include macro

Content by user macro

Any user User macro designed to go through a lot of data

Include Macro can be useful for reusing content. This is common when a single source of truth is required and distributed across several pages. If these macros are used in large numbers (10+) then the page can be slow to load. The page which are loaded in Include Macro can have dynamic content also which can also lead to more lag during load.

If these Macros are excessively used in the page, try removing some. Excerpt Include Macro is also a good workaround, as it loads only the part of the page as opposed to loading it completely.

Confluence becoming sluggish is usually do to some sort of resource constraint.  I would suggest looking at your logs during the times the application is slow.  You should also take a look at this https://confluence.atlassian.com/doc/performance-tuning-130289.html#:~:text=If%20Confluence%20is%20running%20slowly,(or%20around)%20the%20database.&text=High%20latency%20might%20stem%20from,up%20to%20you%20to%20investigate and make sure that your instance is tuned to perform well.

You are seeing a symptom of another issue.  What do the logs say when this action is hanging?  What is the CPU and Ram load?  What is GC doing?  Could you share some more information.

Have you tried tuning your system and making sure it is properly sized?
