    Angry Lightstreamer version 7.2.1 Java SE client

    I have a java client which is connected perfectly to LIGHTSTREAMER version 7.2.1 through https, however, the behavior is not correct, the client receives the data too slowly and it appears like a refresh every 3 seconds.

    Strangely enough, Server version 7.2.1 was not publicly released. Perhaps do you refer to 7.2.0 or 7.2.2?
    There is no factory limitation of one update every three seconds, so the limitation can be in the source or perhaps in the communication.
    We need to see a snippet of the Server log covering a whole client session which experiences the issue.

    Can you replicate the behavior with a test installation of the Server? In this case you can enable the following loggers:
    - LightstreamerLogger.pump at DEBUG level
    - LightstreamerLogger.subscriptions.upd at DEBUG level
    - LightstreamerLogger.requests at INFO level
    and we can trace the lifecycle of the updates.

    In case it only occurs in a production installation, can you check if the Server process is overloaded?
    Alternatively, you can collect the log with factory setting but adding the configuration of the LightstreamerMonitorText logger at TRACE level (which means one monitor line every two seconds).

    Sorry Dario, it was a typo error.

    the version is 7.1.2 not 7.2.1

    Do you advice me to go to the latest version 7.2.2?

    Hi ManKeer,

    I asked for clarifications about the Server version because it was the only context information available, but actually the Server version is not relevant for a reduced frequency of updates.
    To address the issue, I can only confirm my previous suggestions on collecting details in the logs.
    If you prefer, you can send the logs to support@lightstreamer.com

    Only if you notice that the Server process is overwhelmed, an upgrade may be beneficial, but still it would be better to analyze the causes of the overload.
