It’s hard to find a faster download accelerator which works better than the Firefox extension – ‘DownThemAll’. It uses a smart download technique called ‘multipart download’ where it splits files into multiple sections which are downloaded simultaneously. This maximizes the use of bandwidth, and increases average download speed up to 400%.
Speaking from personal experience, I was extremely please with the results yielded during testing, and the download speeds for podcasts were literally blazing fast compared to whatever I was getting earlier. Aside from iTunes, ‘Autobahn’ also optimizes video download speeds from Veoh and Myspace videos. Available for Windows and Mac, Autobahn is free.Google+
