A major feature of Chronicle Queue Enterprise is support for TCP and UDP replication across multiple servers to ensure high availability of client infrastructure, whilst there may be inherent latencies within the network, we want to ensure that Queue replication adds minimal overheads.

The results show that typical latencies varied between 14 and 40 microseconds and the 99th percentile varied between 17 and 56 microseconds dependent on throughput being tested
