Warnock fielded a side featuring the five permanent signings he has made since Tony Fernandes' takeover of the London outfit last month.
"It was probably as complete a performance as you are going to get away from home," Warnock said after seeing Joey Barton, Alejandro Faurlin and DJ Campbell score in the 3-0 win.
"But we have been like that - we were like that on Monday night against Newcastle really, just without the finishing product.
"To get a goal here early doors was really good and then it was followed up quickly by a great second goal.
"I thought we were unlucky not to score a few more. We really move the ball quickly and since all these new lads have come in, training has gone up 30-40% in terms of quality.
"You could see that today - even my old lads were spot on."
