FormatCode function used in mmengine.config.config.py consumes a lot of time.

Every time I debug the code, Runner.from_cfg(cfg) takes a lot of time.
I found that self._log_env(env_cfg) and self.visualizer.add_config(self.cfg) are the time killers which is beyond what I thought.

Then you will find text, _ = FormatCode(text, style_config=yapf_style, verify=True) consumes time the most just as the process is stopping.

Have your team planned to fix the time-consuming problem. I think that log thing taking up so much time is ridiculous.
