在TCP套接字数据发送C＃之间获取恒定的延迟

Question

I have a Client-Server application in C# 2010. In TCP Socket i setup Nodelay = True, and SendBufferSize = 0 for all the connected socket (client-Server) in my application.

I am tracing every incoming-outgoing packets and writing that in logfile using streamwriter, which has autoflush property set true.

I noticed 1 thing that sometimes there is a constant delay (15-16ms) between 2 data packets while sending data. after few continuous sending this delay appears again.

Why this delay? and how can i avoid it....

Answer 1

If you are using DateTime to track your performance 15ms is about the provided resolution. Try using Stopwatch which is more reliable.
