Slow when when a big javascript file is loaded in the dev tool
Hello,
I'm working on a website with Ember.js. There a big "vendor.js" file with 300 000 lines of code where a lot of addons are concatenated. When I open the file in the dev tool, it takes all the CPU and a lot of RAM (at least 2Go). When I reload the page, it takes again a lot of ram. It can go takes 4go for a single tab and 50% of my CPUs. Furthermore, the links are inaccurate in Firedox dev edition and don't match the lines in files. It's worst when the source map is enabled because I don't have to open the big file to have the effect. I'm on firefox dev edition 58.0b8 and firefox 57. It's a lot better when "devtools.debugger.new-debugger-frontend" is false.
Thanks for your help !
