Submitting order taking time (4sec+)

I am trying out the alpaca api. I made a python script to submit orders. But, It is taking around 4 seconds or more.
Is there any way to speed it up?

market order or limit order ?

Have checked order status with api.get_order(order_id)? Have you considered asset liquidity, which you are buying?

I am making a market order.

seams fineā€¦
