This image shows the degradation observed in the overall system throughput in transactions per second for different latencies between the sites (both sites working together with the database in one of the sites).

This image shows a column chart of overall Oracle WebLogic Server (WLS) throughput, measured as transactions per second (TX/sec), versus network latency, expressed as round-trip time (RTT) between sites.

The vertical axis is Java Transaction API (JTA) TX/sec as a percentage, labeled "JTA TX/sec (%)" from 0 to 100. The horizontal axis is "RTT between sites (ms)" with three categories: "0.3 ms, servers in the same availability domain (AD)"; "0.6 ms, servers in the same region, different AD"; and "6.5 ms, servers in different regions."

Reported values: 100% throughput at 0.3 ms (same AD), 100% at 0.6 ms (same region, different AD), and 92% at 6.5 ms (different regions).
