OS X :: Slow Web Sharing / Streaming Speed On Diffrent Pages

I have web sharing on so I can stream all the media on my computer's hard drive to my ipod touch.It works, but the speed performance is pretty terrible. I'm just streaming videos over my local wifi network (not through the net) and the playback buffer on my ipod touch will take a while to start, then there'll be a burst where the buffer starts moving forward reasonably quickly, then it'll suddenly completely stop adding more to the buffer, wait a little while, and then suddenly start adding more into the buffer.

I'm running this on my own wifi network at home, it should be blazing.In fact, I actually get much better streaming speeds into my ipod touch when I actually do watch a video I'm streaming from some other website on the net.
