Should I run Jenkins by command line instead of as a service?

I have been running Jenkins as a service on EC2 for a while. The problem is that since it's being run as a service, the chrome browser size is smaller than what we need. We are now running it using command line (not as a service) so it has a bigger browser size now. The only issue that I've observed so far was that the performance decreased. It took 1:30h for a 50mins jobs.

Should I keep running it using command line? Any other concerns that I need to worry about? (except the performance issue) Thank you.
