Receive Spin Limit

Receive spin limit is an advanced parameter of transports. If you understand the role of threads in inbound message delivery, you can use it to eliminate a potential source of latency by increasing the CPU resources dedicated to inbound delivery.

Warning: Do not adjust Receive Spin Limit except to achieve specific and well-defined performance objectives. Do not adjust unless you thoroughly understand all of the material about this topic.

For an introduction to message delivery, see “Inbound Message Delivery” in TIBCO FTL Development.

  1. Polling for Data
    The TIBCO FTL library polls for available data during two phases of inbound message delivery:
  2. Receive Spin Limit Tuning
    The default values for receive spin limit yield good performance in many situations. When necessary, administrators can adjust receive spin limit as a parameter of individual transport definitions.
  3. Inheritance of Receive Spin Limit From Transports to Dispatch
    Receive spin limit is a parameter of transports, but its value governs the behavior of two delivery phases.
