This feature is implemented in 1C:Enterprise version 126.96.36.1998.
In version 8.3.9, we implemented a significant number of tasks to optimize different mechanisms of the platform. We would like to tell you about one of them in this article. The task in question concerns improved performance of web services.
Reuse of sessions
Insufficient performance of web services was due to the fact that each web service call had significant "overhead expenses" related to creating and terminating a session. Besides, every time a session was created, the handler SessionParametersSettings() was executed, which could be quite "heavy" in a standard configuration.
In addition, there was a functional deficiency. Web services did not have a state. This prevented us from implementing the logic that uses saved state between web service calls.
In version 8.3.9, we fine-tuned the mechanism for web services (SOAP services, HTTP services, and OData services). As a result, their performance has improved by approximately 10 times.
