    Страшно тормозит консоль (nxmc-1.2.16-win32-x64).
    CPU все время 100% на одно из ядер.
    Что можно сделать?

    :~$ nxadm -c "sh sta"
    Total number of objects:     134800
    Number of monitored nodes:   10521
    Number of collectable DCIs:  12833

        Проблема временно решена отключением сетевых интерфейсов.

          Во всех трех дампах исполнялся код, связанный с обновлением списка алармов. Насколько много активных алармов и как часто они меняются?

            Алармов очень много.
            Меняются почти постоянно по 20-30 в секунду.
            Точное количество смогу сказать завтра.
            Основной проблемой был "слушатель" на сетевом интерфейсе, который смотрит в другую сеть. После того как интерфейс был потушен - все стало работать нормально.
