  • readFile load the whole file which you had marked to read whereas createReadStream reads the complete file in the parts of the size you have declared.
  • The client will receive the data faster in the case of createReadStream in contrast with readFile.
  • In readFile, a file will first completely read by memory and then transfers to a client but in later option, a file will be read by memory in a part which is sent to clients and the process continue until all the parts finish.
