gosh, I never spend 30 minutes in security at MCO, let alone at ROC. For the OP, your security experience during the time you mention won't be more than 15 minutes (maybe less) from the time you get in line until the time security finishes violating your bags and body. They don't have TSA in Rochester, it's one of the 6 airports with government contract companies.
I guess you could say ROC is pretty small, but it's all relative. I've been to airports that are much smaller! Ever been to Bangor? Charleston? Or how about CMX? Now that's small.
