I���ve tried this:

[ 'http://picasaweb.google.com/data/feed/api/all?q=puppy' asUrl
 retrieveContents ] timeToRun 0:00:00:02.587

 [ 
GTInspector setGTInspectorEnabledStatus: false
('http://picasaweb.google.com/data/feed/api/all?q=puppy' asUrl
  retrieveContents) inspect ] timeToRun 0:00:00:02.877

 [ GTInspector setGTInspectorEnabledStatus: true.
('http://picasaweb.google.com/data/feed/api/all?q=puppy' asUrl
  retrieveContents) inspect ] timeToRun 0:00:00:50.129

[ 
RubScrolledTextMorph new 
openInWorld; 
updateTextWith: ( 'http://picasaweb.google.com/data/feed/api/all?q=puppy' asUrl
 retrieveContents) ] timeToRun 0:00:00:04.543


So, Rubric takes 2 seconds to open and show this big text, 
the basic inspector takes 0.3 seconds to open but it shows the first characters only.
GTInspector takes 50 seconds.

I think the problems comes from GTInspector itself.
From MorphTreeMorph maybe which is used by GTInspector

Hi,

It takes such a long time because for String objects the default presentation shows the content of the String. In this case the string has 10 million characters which Rubric takes some time to display.

Given you use case it could make sense to limit by default the size of content that is displayed and when this happens add an action for showing the entire content.

Cheers,
Andrei

Hi,

if you inspect the following in Pharo 4, it will take a long time to
execute:

  'http://picasaweb.google.com/data/feed/api/all?q=puppy' asUrl
  retrieveContents.


but if you execute this before, the inspecting above expression is much
faster:

GTInspector setGTInspectorEnabledStatus: false.
