IDE vs. EXE performance in .NET

I've developed a .NET application that, among other things, does the following:

1. Uses WebClient to retrieve data from a remote server.

2. Serves as a socket server to 2 'satellite' applications run on the same machine or on a LAN.

   When I run the app in the VS IDE, it works great. It quickly gets the data from the remote server and communicates perfectly with the 2 satellites.

   However, when I build it and run it as an EXE, the response from the remote server is very slow and its communication with the 2 satellite applications become very poor.

   Is there some important difference between running an app in the IDE and running it as an EXE 开发者_StackOverflowthat could effect it like this?

take care, lee

Without seeing any code, the best advice I can provide is to do some profiling. At the simplest level, this could mean just logging the start/stop of each call (in a log file) that seems slow. It's quite possible that the problem is a different function call than what you believe.

Once you narrow down your problem, you can post the relevant lines of code with more detail so we can help.
