What is the pink column in the waterfall tests ?

[pqdbr]

Hey guys,

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

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.
