Re: [Cppcms-users] 100% cpu usage

[Artyom B. <art...@ya...>]

1. how do you trigger the loop?
2. I don't understand why are you using asynchronous application for the WebAPI. You don't do anything asynchronous. More than that calling blocking SQL from event loop is BAD idea.
 
also is there any way to make it with less dependencies so I can build it
