How to reduce the latency of mysql master/slave data synchronization: bitsCN.com

Generally, the master/slave mechanism based on LAN can meet the requirements of 'realtime' backup. If the latency is high, first confirm the following factors:
1. network latency
2. master load
3. slave load
The general practice is to use multiple slave instances to allocate read requests, and then retrieve a dedicated server from these slave instances for backup purposes only, without any other operations, it can meet the 'realtime' requirement to the maximum extent.

In addition, we will introduce two parameters that can reduce latency.
