The need of large amounts of data requires the availability of data. Distributed database made the possibility of data and information distribution in various places to meet the users need. Replication techniques were applied to support the distribution of data where data is copied in part or in whole then placed in several locations. Data consistencies are needed when applying the replication techniques to make the replica consistent with one another. Client centric consistency is one of the models to support the consistencies on distributed database. Client centric consistency was expected to give a good performance in providing the data to users. MySQL is a database management system that is most widely used. This study aims to implement a client centric consistency in MySQL and then do a performance test. The result is the performances generated by each model depend on the type and number of operations that are applied to the system. The best performance generated by the models that exist on the client centric consistency are Monotonic Reads produce the best performance for the update operation, the Monotonic Writes and Read Your Writes for the select operations, and Writes Follow Reads for the insert operation.
