When a OPC UA node is enabled for monitoring then the CPU usage will be significent

XMLWordPrintable

      When a OPC UA node is enabled for monitoring then the CPU usage will be significent. This is due to the sendPublishRequest() function which appears to continually fire a zero based single-shot timer, as the timeout signal of the timer refires the same slot until m_sendPublishRequests is set to false which happens in modifyPublishRequests().

      Changing the interval to 100ms is enough to circumvent the issue at least.
