Check out my new course Learn you some Lambda best practice for great good! and learn the best practices for performance, cost, security, resilience, observability and scalability.
DISCLAIMER : as always, you should benchmark against your payload and use case, the benchmark numbers I have produced here is unlikely to be representative of your use cases and neither is anybody else’s benchmark numbers.
Adam Sapek explained that the slow serialization speed I was seeing was down to the default buffer size being 64KB which is not suitable for the payload I was testing with.
Adjusting the buffer size to 256 bytes resulting in some pretty amazing result:
Fastest serialization & deserialization, and smallest payload.
Have a look at the performance tuning guide, there’s quite a few tweaks you can do to improve performance further but it’ll depend on your payload.
I specialise in rapidly transitioning teams to serverless and building production-ready services on AWS.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Check out my new course, Learn you some Lambda best practice for great good! In this course, you will learn best practices for working with AWS Lambda in terms of performance, cost, security, scalability, resilience and observability. We will also cover latest features from re:Invent 2019 such as Provisioned Concurrency – what it is and when you should use them. Enrol now and start learning!
Are you working with Serverless and looking for expert training to level-up your skills? Or are you looking for a solid foundation to start from? Look no further, register for my Production-Ready Serverless workshop to learn how to build production-grade Serverless applications!
