Runing 2 cuda processes simultaneously lowers fps
I have used the YOLO repository to train a model.
GPU - GTX 1080 TI (12GB VRAM)
For measuring the FPS, I have written a simple python script that processes video files.
When I run the python script from one terminal on a GTX 1080 TI, I get an FPS of 109 frames per second.
When I run the python script from 2 separate terminals simultaneously, they both print an FPS of 90 frames per second.
Why exactly does this happen? Is it processing sequentially, and not parallely?
I would like to run 2 detection streams with no loss in FPS. Is there a way to do so, some kind of optimization maybe?
