React performance tools is a good starting point. Using those will give you a better idea of where it's using time. You can also use browser tooling to figure out memory usage and how it's manipulating the DOM (flashing at Chrome "Elements" tab). The "Network" tab can be useful too.
If you are using Webpack, you can get stats out of it (--json) and use available stats analysis tools to understand your bundle composition better.
