Given your specs, you're running 3600Hz step rate, that seems reasonable, or maybe on the high end (check this with an expert). However, your 18tpi is one area that is killing your feed rate. With 200oz torque, seems you could go a lot faster. At least change your threads per inch on your leadscrew. 1/2-10 would give you almost twice the rate. You could probably go faster than that. I'm still a newbie so I can't recommend more than that.
