This section provides information about more advanced development techniques supported by the Handler. The topics are grouped by area so you can jump straight to what you need.

Performance and Low Latency

Low Latency Best Practices — disabling logging, tuning working threads, and reducing the time the Handler waits for incoming data.
Hardware Timestamps — measure processing latency using timestamps assigned by the network adapter.

Reliability

Affecting Packet Gap Detection — how the Handler distinguishes out-of-order packets from lost ones and which parameters affect the decision.

Diagnostics and Logging

Diagnostics and Logging — controlling the Handler's log output, the logging example, and the warnings concept.

Handler Topology

Creating Multiple EMDI Handler Instances — create several handlers explicitly without using a handler manager.
