How can I limit bandwidth in Java?

I wrote a Java scheduler, every hour using:

new SAXBuilder().build(new URL(xxx));

or

HttpConnection.connect(new URL(xxx)); // jsoup library code

to get a big XML/HTML file.

My server maximum bandwidth limit is 2Mbits.

When this Java schedule code runs, I use over 2Mbits of bandwidth. (check it out)

So every time a user visits my server it is too slow.

How do I limit my Java schedule to use lower bandwidth? (ex. 500Kbits)

I am using Ubuntu server.
