Browser agent v1194

January 11, 2021

Improvements

Optimized instrumentation of promises

The promise instrumentation has been updated to reduce performance overhead on web sites that use large number of promises.

Issue Resolutions

Fixed issue with SPA overhead

In a rare case where large number of callbacks are executed at the end of an interaction, the agent could cause a significant overhead. This has been fixed in this version of the agent.

Fixed issue with Fetch instrumentation

Updated fetch instrumentation to account for cases when the function argument is a URL object.
