Content indexing issue with High CPU

[Support Eigen]

Hi ,

there is a bunch of pages parent and with child pages  that need to move to another space , when we move these pages  or change permission pages content indexing queue happening and it crushed the pages because of high CPU usage 

I am moving that issue temporarily with this method 

https://confluence.atlassian.com/confkb/how-to-rebuild-the-content-indexes-from-scratch-on-confluence-server-110035351.html

My question is for a permanent solution 

Q1: What is recommended CPU and MEM for content indexing queue finishing faster?

Q2: Is there any limit or reduce that queue with child pages? I mean what is recommended pages that how many child pages need to be 1 parent page for better working content indexing ?

Thanks for your support in advance

Hello @Support Eigen 

Welcome to the Atlassian Community!!

This is very vast topic of discussion. I can see you are using confluence server. The recommended hardware requirements can be found at the following URL: https://confluence.atlassian.com/doc/server-hardware-requirements-guide-30736403.html 

To troubleshoot the confluence indexing, these are the some important points as mentioned in the documentation: https://confluence.atlassian.com/confkb/confluence-indexing-troubleshooting-guide-1035242274.html

Now, the answer of your questions.

A1: Need to the server configuration and application configuration settings on the server. You can follow some of the documentation or might be required to follow more documentation depends upon the identifying the issue.

A2: There is such limit in child page. 
the maximum size of the confluence is recommended to 100,000 characters.

You mention CPU and memory here, which are important, but the indexing is also heavy on the disk.  If you've got a slow read/write on your local disk where the index is stored, no amount of CPU or memory is going to help.
