# 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 your function's execution speed, Weave performs its network activity on a background thread.

<Note>
  When your program is exiting, it may appear to pause while Weave logs any remaining enqueued data.
