Application in C # that collects data from a computer network [closed]

Good evening, I'm developing a C # application that collects data from several computers with logically different IPs, this access is being done at the same time and the information is handled in the application. However, I'm noticing that the system is getting slower, I tried to wipe the code, but I suspect that the error is in this simultaneous IPS access (although I need this information in real time, 14 machines). How can I make it faster and more effective?
