Have you specified the browser that you want to open? How are you calling the browser? Are you using incognito or user profile for the browser?
If you were to do the exact step manually, is it quicker than the automation?
I either have a navigate on top of my test that specifies the URL and browser, or a login test in the first position of the execution plan. Its not the browser, because the same test behaves differently on 2 different computers. Here is the log for the same test on both PCs. If you look at the second step, it waits 20 seconds, on other tests its more. The big project suite runs immediately, the small one waits a bit.
