Serial Communication Baud Rate

Hey guys i recently decided to build a simple XY plotter and i need to use serial communication as fast as possible so my question is does increasing baud rate increase communication speed?

NewStudent: does increasing baud rate increase communication speed?

It definitely increases the transmission speed, it could increase communication speed.

Simple answer is "yes". But only to the point where the devices fail to communicate.

Thank you both for your answers guys!

I regularly use my Uno and Mega at 500,000 baud when communicating with a Python program on my PC.

The way in which serial data is processed can also have a huge impact on throughput. Have a look at the examples in Serial Input Basics - simple reliable ways to receive data.
