Steps to reproduce the problem:
1. Go to a website with largish HTML, e.g. stackoveflow.com
2. Type document.body.innerHTML in the console

What is the expected behavior?
The string appears almost instantly.

What went wrong?
It takes 12 seconds for the string to appear, in both Stable and Canary.

Particularly strings with lots of line breaks seem slow, if I strip the line breaks out of the HTML above the string appears within 2s.

The Timeline view for DevTools shows that most of this time is spent doing a layout.

Did this work before? N/A 

Chrome version: 52.0.2743.82  Channel: n/a
OS Version: OS X 10.11.6
Flash Version: Shockwave Flash 22.0 r0

The string has about 250k characters and 4000 lines. That's fairly large, but it should be possible to display this more quickly. Passing the string into console.log is much quicker.

It's a problem I run into quite frequently and I currently have to self-police myself in case a string I'm looking happens to be unexpectedly long.

After displaying a large string any further output in the console also takes a long time to appear.
