Increase response time via rest api

Im wondering if there is any suggested way of increasing the response time when using the alpaca rest API? For each trade, we fetch current quotes via rest for quantity calculations and then send the order in as a post request. The quote GET call takes 150-300ms and the order processing also takes some time which results in a total of aprox 400-800MS for each trade we do with our client apps using alpaca. I was wondering if there is any approach to increase response time, like is there a way to host apps on the same servers as the alpaca servers? No matter the cost for that.

I cant set up a websocket for every symbol on all US based stock exchanges for faster response times via websocket protocol, cause we do not know for what symbol the next signal will come in initially. SO im stuck with REST.


our current servers are hosted in North VIrgina.
