APAR status

  • Closed as program error.

Error description

  • The HTTP transport has a configuration setting for "Max
    connections per host".  This limits the number of outgoing
    connections to the host configured.  This setting is remaining
    at the default of 20.
    
    SYMPTOMS:
    
    When running a performance test against a web service that
    responds slowly, for example in 500ms, only 40TPS can be
    achieved per test engine.  HTTP connections are unable to be
    started until existing ones are completed.
    
    WORKAROUND:
    
    Run multiple test engines to increase load throughput.
