In this best practice we implemented the Network Time Protocol (NTP), as having computer systems synchronized can be critical for applications and their recovery

Product | Red Hat Enterprise Linux 8.3 |

Day and value | Day 3, Fine Tuning |
Overview
NTP is used to synchronize clocks between computer systems using the network. NTP enabled servers will 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 that implementing NTP on our servers would result in significant performance improvements. The following performance metrics did not change when NTP was running on the database servers:
Implementation Steps
In Red Hat 8, the NTP protocol is implemented by the chrony daemon through the chrony package
Use the following steps to configure the daemon:
