I agree with the others, your warm-up looks decent and isn’t that long, I’d say it’s on the shorter side if anything.
If you feel like a shorter warm-up would help you run better my guess is you’re rushing through your warm-up and getting yourself way too amped. Are you pretty nervous and high strung on race day? You might be expending so much nervous energy in the warm-up that you feel burnt come race time. If this is the case you’ll need a “slow cook the goose” type of warm-up.
