The tutorial

Looker Studio (formerly Google Data Studio) is an essential dashboard tool. However, despite its many advantages, one significant issue is its slow performance. Don't worry, though - you're not the only one facing this issue, and we'll explore different solutions to fix it.

Let's get started!

Why is Looker Studio so slow?

Looker Studio operates by running a query for each new table or graph, waiting to obtain the requested data, and then applying formatting to display the data. These steps are performed for all data sources in real-time, which is the main reason why Looker Studio operates slowly.

This is the process carried out by Looker Studio the first time you request the data, after which it will be cached. As a result, your dashboard will load faster when you open it a second time. However, if you request a different date range or new metrics and dimensions, Looker Studio will need to query the data source again.

ℹ️ Please note that the duration for which the data is cached is determined by settings and depends on the connector used. For more information, please refer to Looker Studio support.

So, your Looker Studio dashboard may run slowly if you:

  • use an excessive number of charts;
  • use too many data sources;
  • use too many dimensions & metrics;
  • use too much formatting;
  • refresh your data too frequently.

How to make Looker Studio faster?

To speed up Looker Studio, there are multiple solutions more or less efficient:

1. Simplify the dashboard

The more charts and tables you have, the slower Looker Studio will be. It's best to create a concise dashboard with fewer metrics and dimensions. Avoid displaying numerous data on a single page, as Looker Studio will take longer to retrieve and display the data. It's better to have multiple pages with a few charts each rather than one page with many.

Consider using a clear and optimized Looker Studio dashboard template, which is available for free and can help you save time while analyzing your data.

2. Split data source by page

As previously stated, Looker Studio will request data from the data source for all charts and sources added. If there are too many data sources on the same page, the loading time may be excessively long. To resolve this, we strongly recommend separating different data sources into multiple pages. Create charts that use the same data source on a page. For example, when creating a social media dashboard, you can confidently place your Facebook Ads data source charts on the first page and your Instagram data source charts on the second page.

3. Minimize filters and calcul

The more filters and data that are applied, the longer it will take for Looker Studio to load the data. While filters are great for data analysis, it's best to use them sparingly!

Cross-filtering is also a part of this, and you can disable it on certain visuals to reduce the use of filters. To do this, go to chart set-up, scroll down to find the chart interactions parameters, and uncheck cross-filtering.

4. Extract data connector

The Extract data connector enables you to choose particular fields from a data source and keep only the essential information. The selected fields will be updated automatically based on the frequency you set, but it’s not a real-time request. Please note that the storage capacity is limited to 100MB.

This feature is useful for accessing specific data or performing exploratory analysis, although it has restrictions on the selected data.

How to create an extracted data source in Looker Studio?

When you're editing a report, go on resource, then manage added data source and search "Extract data":

Click on the Google connector displays.

Then, choose your data source, choose your fields, check auto-update and choose the update frequency.

After that, you can click on "Save and Extract", and "Add".

Your extracted data source is now available on your report!

5. Use Google Sheets or Big Query

Finally, you have the option to use Google Sheets or BigQuery as your database. It's important to note that Looker Studio's performance is most affected by making queries to platforms such as Facebook, Google Analytics 4, Twitter, and others. Therefore, we aim to avoid direct requests from Looker Studio to these platforms by using Google Sheets or BigQuery.

Unlike the Extract data connector proposed by Looker Studio, going through an intermediary removes the 100 MB storage limit. Google Sheets has a limit, but it's hard to reach, and Google Big Query doesn't have one.

Connecting Google Sheets or Google Big Query to Looker Studio will greatly reduce loading times, while still allowing you to use your up-to-date data.

Google Sheets or Big Query?

  Google Sheets Big Query
Pros
  • Easy to use
  • Significantly increases Looker Studio's speed
  • No limitations
  • Large dataset
  • Suitable for complex queries
Cons
  • Take time to set up (choose the data you want to use in Looker Studio)
  • Still a limit of storage
  • Required more advanced set up

Now, we will present you how to connect your data on Google Sheets and Big Query using Catchr’s connectors, then how to connect Google Sheets/Big Query to Looker Studio to create your dashboard!

How do I use Google Sheets to speed up Looker Studio?

1. Connect your platform (source) to Google Sheets

To accomplish this, Catchr provides a Google Sheets Add-on. With this add-on, you can easily import data from over 50 different sources into Google Sheets. Your data will be automatically and regularly updated based on the frequency you choose.

Here's a video that explains how to use it:

2. Create a report and import your data

There are two ways to create your dashboard with the data you've imported:

▶️ Directly on Google Sheets

Click on Extensions > Looker Studio > Create a report

This tab will open:

Check the option you want then click on “Create” button.

Your report has been created with your data!

▶️ Directly on Looker Studio 

Go to Looker Studio, then Create > Report.

Find “Google Sheets” native connector.

And choose your spreadsheet. Check the option you want and click on “Add” button on the bottom right.

You’re data are available on Looker Studio!

How do I use Google Big Query to speed up Looker Studio?

1. Connect your platform (source) to Big Query

To achieve this, you can utilize Catchr’s connector to integrate your data with BigQuery. There are over 50 different sources available. Your data will be updated automatically and regularly, based on the chosen frequency.

Here's a video that explains how to use it:

2. Connect Big Query to Looker Studio

As for Google Sheets, you can create your report from Big Query or directly from Looker Studio.

▶️ Directly on Big Query

From a table in Big Query, click on the Export tab > Explore with Looker Studio

Your data will be imported directly into a new report that you can modify.

▶️ Directly on Looker Studio

Go to Looker Studio, then Create > Report.

Find “BigQuery” native connector.

Now you can use your data from Big Query.

Conclusion

To enhance Looker Studio's performance, you can follow these 5 methods: reduce dashboard complexity, separate data sources by page, minimize filters and calculated fields, utilize the extract data connector, and use Google Sheets or Big Query for data collection. These solutions can also be combined to maximize Looker Studio's efficiency.
