Various Benchmark

This folder will accumulate many examples of operations with its benchmark. With time, it will be added several languages together with its Mongodb library.

The Mongodb used is local installation whether system/current os installation or using Docker to run it in order to avoid network cost timing. We are measuring the lib itself after all, not our network speeds.

For using Docker, we can simply run

docker run --rm -dp 27017:27017 mongo:{version}

with version is the Mongodb version, such as latest or 4.2, or others e.g. docker run --rm -dp 27017:27017 mongo:4.2

Python setup

The Python is using virtual environment (venv) to avoid polluting workspace.
To setup the venv, do

python3 -m venv .
./script/activate
pip install pymongo
pip install motor # used in insertfind examples

to create a Python environment in this particular folder and installing pymongo library.

Nim setup

For Nim examples, it's depended on benchy package so install with nimble

nimble install benchy

and then we can simply run it like

nim r -d:danger testfile.nim

we can add various compile options such as --gc:arc or --gc:orc to see its difference.

Golang setup

As long we have the Golang installation ready, to test we do

go mod tidy
go test -benchmem -bench .

and look for third tab, that has somenum ns/op, as the timing.

Result and Contribution

For this particular (benchmark) examples, any contribution is appreciated to give a nuanced and fair comparison for each language version.
By no means the values are absolute as each app/program for each user's case is different, but this should give better information and perspective.
