4. Not obvious
• Client has to send more info
• query contains list of fields
• -> biggest requests payloads
• Server has more work to do
• query validation
• customise response
20. • Optimising database queries have an important
impact on performances
• GraphQL allows to optimise from client to data
storage
21. • Tested use-case intentionally picked to be
favorable to GraphQL (test assumption)
• Test yourself for your use-case
• Should not choose GraphQL primary for
performances but for features
