# Will Weave affect my function's execution speed?

The overhead of Weave logging is typically negligible compared to making a call to an LLM.
To minimize Weave's impact on the speed of your Op's execution, its network activity happens on a background thread.
When your program is exiting it may appear to pause while any remaining enqueued data is logged.
