Weak API performance when syncing Testresults from Tosca to Jira/Zephyr

[Maximilian Egner]

Hello everyone,

We are facing a challenge in reporting our test results from Tricentis Tosca to Jira and visualizing them via Zephyr. Although the interface is functioning reliably, we are experiencing significant performance issues. Synchronizing our portfolio of 7,500 test cases takes approximately 6-7 hours, which is not feasible given our need for timely results.

Currently, we are using a custom-built portal to connect Jira and Tosca. However, our engineers have mentioned that the performance cannot be further improved due to limitations in Jira's syncing speed.

Has anyone had experience with alternative methods to connect Tosca directly to Jira with minimal effort? Or are there any ways to enhance performance within our current setup?

Thanks in advance for your support!

Best regards

When pushing large volumes of test results into Jira Data Center via Zephyr’s REST API, the bottleneck is usually the sequential creation or update of individual test entities. Each API call incurs indexing overhead and workflow validation, so processing thousands of items in a single run will scale linearly and quickly hit throughput limits. Zephyr’s own [REST API](https://support.smartbear.com/zephyr-squad-server/api/) is optimized for batched operations where available, and using bulk endpoints to post execution results or update multiple test cases in one request can reduce processing time significantly.
