## I get different results when I rearrange my functions

Function order is very important. Just like in math, the order that you place your functions can affect the result.
## Inspect your query request and response
The most common problems are related to the query and response from your data source. Even if it looks
like a bug or visualization issue in Grafana, it is almost always a problem with the data source query or
the data source response. Start by inspecting your panel query and response.

## My query is slow
How many data points is your query returning? A query that returns lots of data points will be slow. Try this:
2021-08-06 08:52:36 -05:00
2020-08-19 12:38:41 -05:00
- In **Query options** , limit the **Max data points** returned.
- In **Query options** , increase the **Min interval** time.
- In your query, use a `group by` function.
