It matters a lot! 1. Response time. A dedicated machine that stores state in-memory from request to request can respond orders of magnitude quicker than one that does not. 2. Resource Efficiency. 1-2 machines running optimized code will cost less than the 10-20 machines (or 100-200 machines) the cloud provider will have to allocate behind the scenes to run less efficient code.
