Perhaps 8K or 10K would be better. Hi Matthew. I am very new to creating pipes and queues and appreciate any insight you could give me with this. I based it off the thought that 900Kbit/s / 8 = 112.5 Kbytes What is the best way to determine queue size? I have done some testing such as downloading a 100MB file and at the same time pinging another host. I did not see any timeouts and speed was about what I expected so I felt comfortable with the queue size but I would like to have my network as efficient as possible. Please tell me the reasoning for 8K or 10K so I can learn. Thanks! Lewis
