Scripts

npm run build: Build the source code
npm run dev: Watch for changes and recompile files on changes

Before running profiles or benchmarks, make sure to run npm run build first to compile the source code to JavaScript, compiled code will be put in dist folder.

Benchmark memory consumption when connecting to multiple network endpoints

Benchmarking scripts are located in folder src/benchmarks

Command to run the benchmark

node dist/benchmarks/benchmark_connect_multiple_endpoints.js -l [library] -n [numberOfNetworks]

Where:

[library] is the library that will be used to connect: polkadotapi, dedot or delightfuldot-poc
[numberOfNetworks] is the number of network endpoints to connect (5, 10, 20, 50, 100)

E.g 1: Connect to 100 of network endpoints via delightfuldot

node dist/benchmarks/benchmark_connect_multiple_endpoints.js -l delightfuldot -n 100

E.g 2: Connect to 100 of network endpoints via polkadotapi

node dist/benchmarks/benchmark_connect_multiple_endpoints.js -l polkadotapi -n 100

Memory consumption benchmark result

The benchmark was running on a Macbook Pro M1 / 32GB RAM - 512GB Storage, NodeJS v18.14.2

The memory consumption can be varied over time depending on various reasons. Below numbers are the average results of 5 consecutive runnings.

Number of network endpoints	@polkadot/api	delightfuldot
5	~ 50 MB	~ 18 MB
10	~ 105 MB	~ 25 MB
20	~ 210 MB	~ 40 MB
50	~ 470 MB	~ 90 MB
100	~ 830 MB	~ 140 MB
