Hello
I’m using Ruby on Jets to deploy a serverless application on AWS Lambda; but I’m noticing high cold start times, especially for functions with larger dependencies. Even with warm instances, occasional cold starts cause delays; impacting response times. I’ve tried reducing the size of my Lambda package, but the improvement is minimal.
Are there specific optimizations in Jets, such as preloading libraries, adjusting memory allocation / tweaking IAM permissions, that can help reduce cold start latency?
Would using Lambda provisioned concurrency or a custom runtime be a better approach? I’d love to hear what has worked for others deploying Jets applications at scale.
I found this guide on optimizing Lambda cold starts: Concurrency - Jets Serverless Deployment Service Minitab but I’d appreciate Jets-specific strategies to improve performance.
Thank you !!
