In this best practice we implemented the Network Time Protocol (NTP). Implementing NTP enables multiple computer systems to synchronize time which can be critical for applications and their recovery.

Overview
The Network Time Protocol (NTP) is used to synchronize clocks between computer systems. NTP enabled servers have a common time reference enabling activities like analysis, audits, and performance tuning. This is not a performance best practice as the goal is to have all our database servers synchronized from the same NTP server.
Recommendation
We did not expect significant performance changes upon implementing NTP. The performance metrics below showed no change when NTP was running on the database servers:
Implementation Steps
In RHEL8, the NTP protocol is implemented by the chrony daemon through the chrony package
Use the following steps to configure the daemon:
