Does the load average of a computer has effect on a robot's response?

Our lab. has two robots and two computers.

I am running the same code for the human following using deep learning with OpenCV, turtlebot is very very nice but Rabbot is very very slow.

I don't know what is the reason.

The first computer with a turtlebot (Ubuntu 14.04, desktop), this is its load average :

$ top

the output:

top - 21:33:31 up  1:12,  4 users,  load average: 0.06, 0.03, 0.05
