When people say "pick up speed," they usually mean that something is starting to go faster. It's like a car that's been driving slowly and then suddenly starts going faster - it's picking up speed. This expression can be used in a lot of different situations, like when you need to finish a task quickly or when someone is running faster and faster. So if you hear someone say "let's pick up speed" or "we need to pick up the pace," they're saying that things need to start going faster than they are right now.
