Hi muruganprofmail,

the delay seems to be a problem strongly related to the Java HTTP Client, which 
boilerpipe only uses for 
demonstration purposes, and related to infoworld.com only (see thread dump 
below).

As documented, the method DefaultExtractor.INSTANCE.getText(URL) is for mainly 
demonstration purposes. 
Boilerpipe is not a crawler. 

Try retrieving the HTML content of the infoworld.com page using your browser 
(or curl, wget, Apache 
HttpClient etc.), save it to dis (or provide it as an InputSource) and re-try 
the demo code (i.e., use a file:// 
URI). I got the results after 30 milliseconds.
