JS Execution (pink blobs) - what do they mean ?

Hi All

I testing a site and Object 19, the JS Execution (pink blobs) go over the 4.5 seconds mark … what does this mean ?

That the file has been downloaded, parsed and the execution has taken this long ? and the blobs are sporadic ? its this due to natural pauses ?

Any thoughts appreciated, as I’m confused about this at the moment.


That means the script is executing at that time. It looks like there is a DOM Content Loaded handler that runs and then more hooks that run either on a timer or as other events trigger (callbacks of some kind in the code).
