Please give a brief summary of your issue:
Performance degradation when accessing PDFTron features from the US region (Web and Mobile)

Please describe your issue and provide steps to reproduce it:
Hello,

We are experiencing a performance issue with the Apryse (PDFTron) SDK when our application is accessed from the United States. The same workflows operate significantly faster when accessed from Turkey or Europe.

Observed behavior:

  • Slow PDF loading, rendering, and processing when accessed from US-based networks.

  • Issue occurs consistently on both web and mobile applications.

  • No major performance problems outside the US region.

Steps to reproduce:

  1. Access our application from a US-based IP/network.

  2. Open any PDF document using the PDFTron viewer.

  3. Observe slower loading/rendering compared to EU/TR regions.

  4. Repeat the same test from Europe or Turkey to see the performance difference.

We suspect this may be related to CDN routing, service endpoints, or license validation latency.

Additional request:

While you wait for one of our customer support representatives, I can help you with your question.


It seems you’re experiencing a performance issue with the Apryse SDK when accessed from the US, which could be due to network-related factors such as CDN routing or service endpoints. Here are some technical considerations and steps you can take to diagnose and potentially resolve the issue:

Some things you can try:

  • Check the CDN configuration to ensure optimal routing and caching for US-based requests.

  • Test network latency and bandwidth from US locations to your server hosting the Apryse SDK.

  • Verify that the latest version of Apryse SDK is being used and is configured correctly.

  • Investigate if there are any regional service endpoints that might affect performance for US users.

  • Consider implementing performance monitoring tools to log and analyze network requests and responses.
