 * http://stackoverflow.com/questions/1062113/fastest-way-to-write-huge-data-in-text-file-java
 * 
 * I have to write huge data in text[csv] file. I used BufferedWriter to write the data and it 
 * took around 40 secs to write 174 mb of data. Is this the fastest speed java can offer?
 * bufferedWriter = new BufferedWriter ( new FileWriter ( "fileName.csv" ) );
 * 
 * You might try removing the BufferedWriter and just using the FileWriter directly. On a modern system 
 * there's a good chance you're just writing to the drive's cache memory anyway.
 * It takes me in the range of 4-5 seconds to write 175MB (4 million strings) -- this is on a dual-core 2.4GHz Dell
