Performance
The following graphs compare the performance of a single database accessed via normal JDBC vs. a cluster of two identical databases accessed via HA-JDBC.
Read Operations
By distributing read operations to each node in the cluster, HA-JDBC is able to achieve better performance under load than normal JDBC access.
Write Operations
By performing write operations in parallel to each node in the cluster, HA-JDBC is only slightly slower than normal JDBC access. The slight performance loss is largely due increased network traffic and parallel processing overhead.
