Hi Ayush, there are a number of things that can contribute to slowless of a project.
Are you dealing with chronic slowness, or is it just occasional?
Does the slowness occur across all projects? Across all browsers?
I know I ran into some slowness when I was working with a data set using over 500 million hits, had an aggressive filter applied, and applied a breakdown to 400 values. I would expect that to run slow. Do you hit a threshold with slowness after doing a certain action?
