I just install Brave for first time. The thing is, that Brave is incredibly slow on startup. It takes more than 8 seconds to load, while all other browsers I use, start almost immediately. I’m running it on Windows 10 / 64bit platform.
This is a known issue and we have an issue logged for tracking it. I’ve added +1 on your behalf
Also this would be fixed once we move into brave-core. You can read more about it here
