What is the pink column in the waterfall tests ?

Hey guys,

First of all, I would appreciate any tips for optimization in our waterfall below :slight_smile:

But not only that, I’d like to understand what goes on in the pink column in the waterfall (it happens before “start render” starts).

Also, any ideas why we get a gap from resource #12 to resource #13 ?

Can parallell connections be increased any further ?


Thanks in advance !

The pink section is the execution of the DomContentLoaded event. Generally this means you have a lot of expensive javascript attached to $(document).ready() (or some equivalent). The gaps are probably caused by the same javascript execution.
