<DIV>hi there,</DIV>
<DIV> </DIV>
<DIV>a question here about optimazation the Ethernet link, hope get some advices here..</DIV>
<DIV>I connect the hardware to computer platform Window Xp. My software platform is Visual C++, and the client / server model is done though WinSock programming.</DIV>
<DIV> </DIV>
<DIV>The connection all right, server and client "talks" fluently, however, the speed not so satisfyied. <FONT color=#c00000><STRONG>Is that a way to reallocated the internal memory(buffer) size in PC?</STRONG></FONT> Though some studies, get to know that the PC will only start to process data when the buffer size reach certain amount of data.</DIV>
<DIV> </DIV>
<DIV>Thanks for any comment and advices, i am much appreciate.</DIV>
<DIV> </DIV>
<DIV>reagards,</DIV>
