Help to analysis, what's blocking content from loading.

First of all merry Christmas everyone!

I have some problems with content being blocked during loading - please see the screen shot:

Is it the large HTML that’s being loaded the causes the “block” between 0.9 to 1.8 sec., or do you have any other suggestions?


My guess is that that is a break between the and the and it’s all of the stuff in the head that is causing the break. That’s a pretty huge time to load a few of those css and javascript files, are they really large and uncompressed?

It’s also possible that there is something on the back-end that is delaying the page after the head (maybe it gets flushed once at the end of the head and then does a lot of expensive work before flushing the rest of the page).
