My plots are rendering 1 at time

I’m not sure if I triggered something to slow the render process, I switch between local and CDN hosted JS files. My scatter plots are rendering 1 at a time and I can only get about 8 to render now.

I am using Chrome as my browser, my code is hosted in cshtml file I am dynamically loading the the Data array from a WebAPI call this is very vanilla POC code.

It was rendering much faster the other day, I am concerned I might have done something settings wise to kill the render process, debugging was turned on and off within VS 2017 as well.
