If you load all the dependencies outside of the actual event loop, then these will only be loaded in a function's cold start before it is suspended between requests. With this, you're only effectively paying this cold-start costs on first load of a new function (or whilst adding extra concurrency) and they're often kept around for 4-8 hours, even if they don't receive any requests.
