AWS Lambda Memory Performance Benchmark

Motivation

• Understand how RAM selection affect Lambda's performance (on Medium <https://medium.com/epsagon/how-to-make-lambda-faster-memory-performance-benchmark-be6ebc41f0fc>_).
• Code a tool that measures Lambda function performance (duration and cost) with several memory sizes.

Setup

.. code-block:: bash

git clone [email protected]:epsagon/lambda-memory-performance-benchmark.git
cd lambda-memory-performance-benchmark/
pip install -r requirements.txt
python benchmark.py -f <function_name> -r <function_region> -p <payload_filename>

Usage

Basic run:

.. code-block:: bash

python benchmark.py -f lambda-performance-benchmark -r us-east-1 -p fibonacci-function/payload.json
