JAR size affect the response time of lambda?
0
Hi,
I'm making some experiments regarding the impact of JAR size on Lambda Cold Starts and response times. I have created 3 JARs of different sizes.
| JAR Size | Response time |
|---|---|
| 10mb | 1s |
| 64mb | 6s |
| 100mb | 12s |
In Cludwatch logs I can see that init durations for all these Lambas is on average ~620ms, but for every lambda the response time is different and I don't know why. The code is the same(there is no logic -> all of them are returning a String), differences in size are due to different maven dependencies that I added. All of them are from AWS SDK. Is this normal?

Yes. the size of function package can affect the cold start time. You can refer this blog (https://aws.amazon.com/ko/blogs/compute/operating-lambda-performance-optimization-part-2/)
