When a single workflow feels slow

Start by finding the API endpoint that is causing issues.
When the Function stack is executed within Xano, you'll be able to see each statement's response time.
Example
This API endpoint takes a Star Wars planet name and returns information about the planet using the Star Wars API (swapi.dev). They don't have an API that searches a planet by name so this function stack has to recursively loop through the returned planets and match up the user's request.
A. There are technically three (3) items in the function stack.
B. After you click Run & Debug, click the debugger tab to see the results and response times.
C. You'll see that while there were only three functions, 14 statements got executed. This is because Function 3 is a For Each loop that goes through each result of what is returned by the API and creates a variable.
D. You'll see that the total response time is 5.39s which is quite long for a response, however you can also see in Line 1 of the Debugger that the Star Wars API request is taking 5.37 seconds to return a response. Xano's execution of the request happens much faster.
If you are experiencing slowness with Xano and can't figure it out on your own, you can contact support.
Please carefully read the following to resolve your issue as streamlined as possible.
Have you tried the debugging steps listed above to narrow down problematic requests or steps in your function stack?
If you are having an issue on your front-end, have you taken the necessary steps to ensure that everything is set up correctly on your front-end to use external data sources (like Xano)?
If you have taken the steps to troubleshoot your endpoint, please make sure that you prove the following information when contacting support.
Please provide the following details:
Workspace name
API endpoint/function/task that is slow (please include the URL in your address bar)
JSON payload, if you are passing data
Email or user ID, if authentication is required
Screenshot of your usage graph and API request graph
Other helpful information (describe the issue in detail), for example:
Is this always slow? intermittent?
Is this endpoint returning records? If it is, how many records is it returning, and does the amount of records seem high for what you are expecting or is it normal?
If you do not provide all of the information listed above, your support request will likely receive a delayed response
Workspace name: Example API endpoint: https://x07d-e032-f135.n7.xano.io/admin/workspace/1/api/2/query/13 JSON data payload: {"test": "hello there", "value": 123} Authentication: Yes - user: test@email.com Additional information and description of the issue: "This API endpoint seems to always be unusually slow. I'm experiencing a response time of x seconds. The endpoint is returning 25 records and the response looks to be correct. Let me know if you need any additional information"
Workspace name:
API Endpoint URL that is slow:
JSON data payload (if you are passing data to the API endpoint):
User ID or email address (if the endpoint requires Authentication)
The team will review with you the actions you have already taken as detailed in our above, and make any recommendations for additional efficiency. Please understand that every Xano plan has its limits, and our ultimate recommendation may be to upgrade to a higher tier plan, but we will do everything we can to address outstanding issues before this.
We understand that sometimes waiting isn’t an option. There are multiple other avenues that you can take to get support with Xano.
If you have already addressed efficiency concerns in your database and function stacks as detailed in , the next step is to upgrade your Xano plan for improved performance.
Have you consulted the Xano and the documentation on this issue?
