NestJS Performance Analysis

This is the artifact of my performance analysis on NestJS about ModuleTokenFactory.

H4ad

This file was used to perform a performance analysis on object-hash.

To run, copy all files to a folder, initilize the NPM with npm init, then install:

npm i --save benchmark object-hash

H4ad

Results:

fromUnixToISOString x 3,258,470 ops/sec ±1.86% (85 runs sampled)
new Date().toISOString() x 1,408,158 ops/sec ±0.96% (90 runs sampled)
