Last time I used JSDOM it was leaky, So I switched to cheerio. My two cents.

Jsdom have terrible performance, so think about using "cheerio" instead.
As for cpu-intensiveness, you have plenty of options here. Easiest
solution would be to increase an amount of node.js processes using
"cluster" library. But the best way is to write another node.js server
that would do all blocking tasks, so your frontend would be a bridge
between that server and the user and it would be always responsive.

Hi,
This is a post to get some suggestions over DOM Manipulation
using JSDOM in nodejs.
We have currently written a service which crawls given url on the
fly and input it to JSDOM to inspect DOM with jQuery.
We see that this service consumes 90% of CPU [Expected]. The urls
scraped are quite heavy in their html content and around ~100 req/sec
As the task is quite CPU intensive [not really async aswell] we
feel that when concurrency of requests increases our service goes
unresponsive.
Are we missing out something?
