Go to https://www.textcompare.org/json/json-to-html/ Paste the sample JSON into the input box Click on "Process" Nightly: https://share.firefox.dev/47fhBKD Chrome: https://share.firefox.dev/3G3d1mZ The difference may not look that big in these profiles with a relatively small input JSON file. With a larger JSON (28MB), Nightly basically spend 2minutes+ in GC before I got tired and quit. Chrome completed the task in ~40 seconds. Profile with a 28MB JSON: Nightly : https://share.firefox.dev/47f5Wvr (GC heavy part takes 85s+) Chrome: https://share.firefox.dev/3QVl3o5 (GC heavy part is 26s) The caveat being that this is probably an edge use-case.
