# Performance tips

## Graphite

Graphite 0.9.14 adds a much needed feature to the JSON rendering API
that is very important for Grafana. If you are experiencing slow load &
rendering times for large time ranges then it is most likely caused by
running Graphite 0.9.12 or lower.

The latest version of Graphite adds a `maxDataPoints` parameter to the
JSON render API. Without this feature Graphite can return hundreds of
thousands of data points per graph, which can hang your browser. Be sure
to upgrade to
[0.9.14](http://graphite.readthedocs.org/en/latest/releases/0_9_14.html).
