On the preferences window, click the Advanced tab...
At the top it says 'Multipart download', move the slider to the right to increase the number of segments/chunks.
You can set it to the max of 10 and if the site allows that many it will use all of them. If the site only allows 2 simultaneous connections it will only use 2, etc.

You just need to test which methods work best for which sites.
