Description
I'm using oatpp web service framework and it's amazing and accelerating my backend dev works. However when I am running the oatpp api client demo and found out that the API calling is too slow.
I added the profiler for each API calling to test the time elapses.
As we can see the demo code implementation Code Snippet 1 and its running result in Code Snippet 2.
The http query responding time varied. Ranging from 300ms to 2100ms. Is the normal performance of the client side of oatpp? Is there something wrong within the demo code?
Any suggestions would be appreciated.
