# Troubleshoot queries **** This documentation topic is designed for Grafana workspaces that support **Grafana version 10.x**. For Grafana workspaces that support Grafana version 12.x, see [Working in Grafana version 12](using-grafana-v12.md). For Grafana workspaces that support Grafana version 9.x, see [Working in Grafana version 9](using-grafana-v9.md). For Grafana workspaces that support Grafana version 8.x, see [Working in Grafana version 8](using-grafana-v8.md). This page provides information to solve common dashboard problems. **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. For more information, refer to [Inspect request and response data](v10-panels-panel-inspector.md). **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: + 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.
