C# .NET receive data from Arduino. Textbox output speed(per second)

Question

I want to receive sensor data from Arduino, and show data using textbox(or another way).
Receiving data was successful.
When i checked in arduino, data output speed is (maybe) 80/sec
But in c#, data output of textbox has slowed down.
It looks like pouring water into a funnel...
Is there a maximum speed that the textbox can print?
I want to show sensor data in real time. Not buffer
What should i do?

Answer 1

Have you tried setting double buffering?
