I am trying to develop a multimedia site and I am leaning heavily toward Silverlight however Flash is always a main player. I am a Speed and performance type developer. Which Technology will load fastest in the given scenarios? 56k, DSL and Cable?

It all depends on what you’re doing: animation, video, calculation, etc? There are some tests that show Silverlight being faster for raw computation, while Flash’s graphics engine is farther along (GPU utilization, 3D, etc.).
If you’re talking about load time, there are definitely things you can do in Silverlight to make your XAP file smaller than most images – the Hard Rock Memorabilia team got their XAP down under 70K, and that site browsed GB of photo data. I’m sure you can do the same in Flash.
While your question is focused on performance, as others have mentioned you do have to take into account the 4.5MB install for Silverlight, since it’s not widely installed yet.
