  • Are you trying to render dozens (or hundreds or thousands) of time-series on a graph? This can cause the browser to lag. Try using functions like highestMax (in Graphite) to reduce the returned series.
  • Sometimes the series names can be very large. This causes larger response sizes. Try using alias to reduce the size of the returned series names.
