Hi, I'm looking some advice on response times for BuildShip, I'm currently using the Starter package and quering data from Firestore and I'm surprised by how low the response times are. Now, to be honest, I haven't looked into the reasons too deeply, so maybe it's not BuildShip and there's some other bottleneck.
I did however noticed the following terms on the pricing cards: "no cold start", "Fastest processing tier". Could someone help me compare the packages in terms of response/compute speeds? "no cold start", "Fastest processing tier" don't necessarily have any relevant meaning, or am just too dumb to understand it
