Hi again Robin2,
I used Gnu profiler to try to fine the bottle necks in my software. For the embedded syste, I got the data rate up to 12MBS, also for the client running on my laptop. The problem was I was using commands to find control characters, such as 'newlines' for parsing the data. Now those commands examine data a single byte at a time, obviously they were wasting alot of time. Also, as you noticed, I was passing the 'strlen' function to every call to send. Now, I create an array of integers that hold the string length, and just pass the cell of the array into the function call. That speeded things up by a little. Think I've taken it as far as it will go on my laptop. I'll need to find another way to generate data bursts for rate testing.
Thanks for hanging with me on this issue.
