We actually keep a pool of browsers ready so when a request comes we just assign it to an already running browser. This way in most situations there is no actual waiting for chrome to startup!
Ah of course, makes total sense. Thanks for answering!
Is each browser process dedicated to a single customer, or do you clear cookies and other state (localStorage, cache, Chrome advertising features...) between customers?
We use a new browser for each session you create! We don't share the browsers between different customers.
