Hi, a somewhat Newbie question… What performance improvements can I expect if I migrate a MySQL 5.7 instance running on a single machine to a XtraDB cluster with 3 nodes running (assuming the same hardware and OS etc as the single instance). I ask as I want to work out if moving to a cluster is a going to improve the performance of the DB and in what way. Presumably I will be able to have more concurrent connections… but how many more? What is the overhead of running a cluster? Will individual queries be quicker/slower? I would be setting this up in an AWS EC2 environment… so network latency should hopefully be minimal… Any hints, experiences etc would be appreciated… Thanks, Karl ---

XtraDB cluster will not increase your database performance. Actually, It provides High Availability and scalability. And it 's better to have a Proxysql or Maxscale to work with your XtraDB cluster.
