The faster Lambda runtime - NodeJS or LLRT? We benchmarked.

LLRT is a Low Latency Runtime for AWS Lambda built with QuickJS & Rust. Can it replace NodeJS? LLRT reduces your Lambda cost by 2x, and cold start by 10x.

Love this article!!

I was wondering if the NodeJS size of 160MB includes the AWS SDK for a fair comparison. From what I've seen, NodeJS is usually 25-40MB otherwise.

Hi Garik, thanks for your comment.
If you download NodeJS for Linux from the official site, you'll get to see the size of the entire package after unzipping it.

If we include AWS SDK as well, then the size will be increased.
If cold start is your concern it's best to bundle AWS dependencies as well.
