I am working on a proctoring software. In it, I am using tensorflow.js and coco-ssd model. The configuration of the system(PC), which I am using is 16 gigs of RAM and 120 GB SSD. The processor details are as:- Intel® Core™ i5-4570 CPU @ 3.20GHz × 4

Also, it currently does not have any graphics installed.

My issue is that my system becomes slow. I, also tested the same on a laptop with 2GB of graphics installed, it ran quite smoothly compared to the PC, which doesn't have graphics installed.

Can someone please suggest to me some ways, to optimize the code or some other solution, so it can run with minimal lag on any device?
