Error description

  • Spectrum Control user interface is slow to load, especially when
    viewing performance data and charts.
    Currently, the GUI code only allows for a single thread to
    process performance data requests.  This means that each
    performance chart/table is queued up waiting for the prior to
    complete instead of being run in parallel.
    This is also observed when trying to view tables with data about
    storage pools.  When the queries are run to calculate the value
    of the 'Activity' column, it queues up behind all prior
    performance queries and only rendered the table after all of the
    prior requests complete.
    RECREATE STEPS:
    Observe slow GUI response when viewing performance monitor data.
