  • CPU usage

    I went back to the client's house with Jandy issue. With following components:
    On this project I have one NI2100 and one NI3101.
    NI2100
    RS232 #1 AutoPath Video Matrix
    RS232 #2 Jandy AquaLinkRS
    RS232 #3 DSC
    IR .....
    IP Control: Lutron RadioRA2 2 systems with 150 dimmers
    IP Control: Zigbee gateway with 4 R4 remotes
    2 Termostates


    NI3101
    RS232 #1 Integra Receiver #1
    RS232 #2 AMX Tango 12 Zones
    RS232 #3 Integra Receiver #2
    RS232 #4 Integra Receiver #3
    RS232 #5 iPort #1
    RS232 #6 iPort #2
    IR ...
    IP Control: 2 Panamax conditioners
    5 TouchPanels.

    NI3101 average cpu usage with one iPort enabled is 10% to 15%.
    NI2100 average cpu usage was 77%, I disabled Zeroconfig then rebooted the
    processor. The average cpu usage was at 54%. I checked the processor cpu usage remotely today, two weeks later and it's 78%.
    Is this comment CPU Usage percentage with specified components above? Why would the CPU usage change so much????? I appreciate your feedback.

    I've come to accept random CPU Usage numbers as clear indication of absolutely nothing.
    Take it as a religious experience, decide what it means to you, then defend that in online arguments, and you're officially a forum member.

    To whit, a recent discussion in a different topic:
