  • Ensure that immediate content is loaded first before future content.
  • Ensure correct URLs and endpoints are used throughout the app
  • HeadSpin analyzed the analysed the initial screens of the Magister app on a real iPhone 8 in London, on T-Mobile.
  • NO SDK, code change or instrumentation was needed to run the remote performance sessions.
  • HeadSpin’s AI engine sifted through network traffic, client-side metrics, and videos of the test execution to find areas of poor user experience and performance bottlenecks.
  • Recommendations were provided for every issue that was surfaced.

Insights and Recommendations

HeadSpin’s proprietary AI technology analyzes and prioritizes the core issues impacting critical user journeys. Using computer vision techniques to quantify blank screens, time to interact, loading time, loading or buffering animations, and content quality, our AI models can automatically diagnose server-side issues whether they arise from infrastructure deployment issues, poor performance, or API errors.

Issues Found:

Low Page Content

As a general good practice users should not look at an empty screen for longer than 1 second, especially during the initial onboarding, signin and signup stages.
We have traced the long waiting time to be due to the below reasons.

1- Slow TLS connection

The application waited longer than 300 ms to complete TLS handshakes with these hosts.

Method: POST
Impact time: 1.8sec

HEADSPIN RECOMMENDATION: TLS handshakes add latency to requests due to additional round trips between the device and server. Consider moving your servers closer to users or using a CDN to cut down on round trip time or investigate yout TLS procedures and protocols to fix the slow TLS connection.

2- Slow Server

The application waited longer than 500 ms to receive the first byte in HTTP responses from these hosts.

Method: POST
Impact time: 838ms


HEADSPIN RECOMMENDATION: If this waiting time is longer than expected then you can investigate the server side implementation further in order to pin down what is causing this issue. If this is expected, we recommend you exploring server optimization techniques and caching data that doesn’t require to be fetched and only fetching data that the app will consume in every context.

3- HTTP Redirects

These HTTP responses are redirects where the original request returned a “Moved Temporarily 302” response code.

URL 1 | URL 2


HEADSPIN RECOMMENDATION: HTTP redirects can be costly, especially if they redirect to a new host, which can incur additional DNS, TCP, TLS, and request-response roundtrips and thus add unnecessary delay. Ensure that the correct urls and endpoints are used throughout the app.

You can try the below steps in order to reset the directives in your .htaccess file which might help with the redirects issue.

Step 1: Open . htaccess file on the server. To identify the web server, you need to find the key file.

Step 2: Find the mod_rewrite directives.

Step 3: Reset the directives in . htaccess file
