How Can I Reduce Cold Start Latency in AWS Lambda?
Asked by
CuriousCoder42
I'm experiencing issues with my AWS Lambda function where it's starting cold on every request, leading to significant latency in response times. I've been using the AWS Parameters and Secrets extension, and it seems like either the Lambda is cold starting for each request—not just the initial one—or the extension is failing to initialize properly each time. Does anyone have insights on how to diagnose or fix this? I've set up my Lambda using a Dockerfile that installs the extension, and I'm concerned that the way it's set up may be contributing to these cold starts. Any help would be greatly appreciated!

Hey there! Sorry to hear about the trouble. I found a doc that offers tips on reducing cold starts. You can check it out [here](https://go.aws/3TElEen). If you still need more help after that, AWS provides additional resources [here](http://go.aws/get-help). Good luck!

CuriousCoder42: Thanks, Matt! I tried setting up provisioned concurrency, but it didn't help with the latency. I'm starting to think that the extension might be crashing and causing the Lambda to restart each time.
