+A second use case of the `MYSQL_DSN` setting is to avoid the golang
+driver executing some statements using prepare and close statement
+steps. This adds a tiny bit of extra latency for queries sent to
+the backend database.  Adding the additional setting
+`interpolateParams=true` to the DSN will avoid these stages thus
+reducing the number of round trips made when making queries.

 #### MySQL/MariaDB configuration
 
 The `performance_schema` database **MUST** be enabled for `ps-top` to work.
