Need to speed up the model creation process of OpenNLP

[nikhil jain]

Hi,
I am using OpenNLP Token Name Finder for parsing the unstructured data. I have 
created a corpus of about 4 million records. When I am creating a model out of 
the training set using openNLP API's in Eclipse using default setting (cut-off 
5 and iterations 100), process is taking a good amount of time, around 2-3 
hours.
Can someone suggest me how can I reduce the time as I want to experiment with 
different iterations but as the model creation process is taking so much time, 
I am not able to experiment with it. This is really a time consuming process.
Please provide some feedback.
Thanks in advance.Nikhil Jain
