UDP “Connect”-Speed in C#

Question

I profiled some boilerplate UDP code and the speed was very good for sending only some small amount data (which is my intent).

BUT the \"connect\" method is \"very slow\

Answer 1

udpClient.Connect sets the default host name and port, so subsequently you can call Send without specifying them. What's taking the time is the name resolution - translating HOSTNAME into an IPAddress.

If you do it once in Connect, you don't have to do it every time you Send, which is faster.
