Adlago Posted September 9, 2020 Posted September 9, 2020 To increase site performance, and to improve loading speed, I think it's time to remove java script codes used in obsolete browsers. Here is an example from a test - removing these obsolete java scripts will reduce the volume by about 11 kbps. or this will shorten the java script download time by about 150 ms
