The original poster was talking about a streaming application -  
increasing the frame size can cause it take longer for frames to fill  
a packet and then hit the wire increasing actual latency in your  
application.

Probably doesn't matter when the stream is text, but as voice and  
video get pushed around via IP more and more, this will matter.
