This chart shows the overall performance of the cluster (Overal % WLS Throughput (TX/sec) with latency (round-trip time (RTT) between sites in ms), depending on where the servers are located. The reference (100%) is when both servers run in the same availability domain (AD) as the database.

The vertical axis shows Java Transaction API (JTA) transactions per second as a percent. The horizontal axis label shows round-trip time (RTT) between sites in ms.

The three bars show:

• 0.3 ms RTT with servers in same AD maintains 100% throughput
• 0.6 ms RTT with servers in same region, but different AD, maintains 100% throughput
• 6.5 ms RTT with servers in different regions maintains 92% throughput
