How to automate profiling in a real browser?

Question

JavaScript

The bottom line is, we are fighting for every 100 ms when rendering a page, but we are faced with the fact that it is difficult to simulate ideal conditions in the developer's environment, many running processes (IDE, etc.) indirectly affect the performance of the browser and, accordingly, the results of manual measurement
There was an idea allocate performance testing to a separate clean server, and measure the rendering speed with each commit:
- it is necessary to check in turn in different browsers (desktop versions of Chrome, FF, IE, if possible in mobile ones)
- record the entire profiling
What tools are there for this? I would like to achieve full automation, as well as conveniently view the history and profiling for each build (with blackjack and charts)
