Mango performance issues on Windows 10 PC


  • Hi,
    I would like have some advice on the performance issues I have experienced on
    a Windows 10 PC.

    The internet uplink speed from the PC to outside world is 536 Kbps where its downlink speed is 13. Mbps.

    Environment of Windows 10 PC:
    i7 3.6Ghz CPU/16GB RAM/256GB SSD with Windows 10 Pro and Java 8 Update 221.
    The CPU is less than 6% occupied and RAM is 53% used.
    There is a Windows IIS based web server running on this PC using port 80.
    Mango 3.6.5 (free version without NoSql) is installed running on the PC using port 8080. There are a total of 256 points in the database. All have 5 minutes interval logging configures. The main data source is a BACnet/IP. Mango has been allocated 3.6GB ram for the Java with free ram of 1.9GB as this moment. The H2 SQL Database size is 1.8GiB.

    I have recently added a custom dashboard page to display historical data for 4 points with various period ranges and statistic selection .

    I have noticed very frequent loss of connectivity to the server Mango UI when I access it remotely and I have the same kind of lag and loss of connectivity when locally working and accessing the Mango on the PC.

    Previously, I noticed loss of connectivity to the Mango UI when I use the watch list chart to pull up the same data but it is not as frequent as now when I access the dashboard.

    Once I navigate away from this dashboard page or the watch list charts to other items inside Mango, the loss of connectivity disappears. So it seems to have something to do with the history database. I am guessing the moment I bring up my dashboard page or the watch list chart, a query for data is sent to the Mango and it is busy extracting the data until such time the task is completed which causes the sluggish response of the UI.

    From the internal metrics, there is '1' high priority work items currently running, there are '222' currently scheduled high priority tasks and there is '0' high priority tasks queued.

    I can provide the MA.LOG and another log file if you are interested.

    Below is code snippets within the div for the dashboard:
