Newbie needs advice on simple project

I'm using the 5V from the board. If I write 180 to the servo, delay just long enough for it to do the full sweep, and write 0, doesn't the servo go at max speed if it's a 5V servo getting 5V? I'm testing with a servo pulled out of an RC project. I probably just need a faster servo, but then I sacrifice torque, which I need also. I'm more worried about the switches being wired and coded correctly at this point.
