Invision Community 4: SEO, prepare for v5 and dormant account notifications Matt November 11, 2024Nov 11
Posted July 9, 20222 yr When a browser performs "parse html" - there is a task being performed that I can't determine what it is. This task creates a large delay when booting mobile. Does anyone have any idea what this task is?
July 12, 20222 yr Community Expert Management I'm unsure what this could be, outside of it actually parsing the HTML and setting up JS handlers, etc.

I put this topic here because there is a strange moment in the FCP time measured in the PSI test. Test 1 - measured FCP for 4G network - 2 sec, FCP time for 3G network 3.93 sec - this is relatively good Test 2 - FCP time for 4G - 3 sec, but FCP for 3G - over 7 sec,... - bad and other indicators Test 3 - FCP 4G - 1.5 sec, FCP 3G - 3.01 sec. - very good. These 3 tests are I done at an interval of 30 seconds This type of results are obtained consistently - in sequences of tests in different time range, but in all three variants of these tests - server is working OK, no delays from the server. Is there some php function that reports access from different G networks?
July 15, 20222 yr Author PS. The same results are obtained in a performance test with the Chrome browser development tool. Now I did about 10 performance tests on your site - I will not upload pictures to accumulate unnecessarily - but time for this task in each test plays from 140 to 350 milliseconds. What does it do and what is that task, that is the question…:-)

I am not sure but all 3rd party java script slow loading mobile. I can attach pictures of different tests. But there is another thing - the promote widget creates a rather large delay when loading mobile. A few tasks that slow down first paint and first content... I personally stopped using the promote widget for my mobile view... Loading speed is more than 10 points better... I looked at your site - this widget is already missing here... Does your development team have thoughts on it?
