That's not unusual. The posts I've read recommend keeping the Rs under 3K until that needle really starts moving. ~10 minutes warm up isn't unusual in my 98.
Unless someone suggest otherwise, I wouldn't be concerned.
My other cars warm up much faster....half the time or better.

No way these cars warm up in less than 5 minutes unless you are low on fluid. A reasonable time, driving reasonably slow to start (2 to 3k rpm) is anywhere between 5 to 10 minutes depending on outside temperature.
