Weird performance behavior #370
Description
const Turndown = require("turndown");
console.time("2500");
new Turndown().turndown('<img src="1" />\n'.repeat(2500));
console.timeEnd("2500");
console.time("5000");
new Turndown().turndown('<img src="1" />\n'.repeat(5000));
console.timeEnd("5000");
console.time("10000");
new Turndown().turndown('<img src="1" />\n'.repeat(10000));
console.timeEnd("10000");In my machine (Mac mini (M1, 2020)) the log is as follows:
2500: 505.093ms
5000: 1.891s
10000: 7.371s
The time spent does not seem to increase linearly. When the image tag count reaches about 10,000, it takes about 7s and caused serious performance problems.
