I found the "Directory server tuning" link directs to a RedHat page with a 404 https://www.freeipa.org/page/Troubleshooting/Directory_Server

The broken link is: https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/8.2/html/Performance_Tuning_Guide/system-tuning.html

Would someone mind pointing me to the relevant page? 

Sincerely,
