forker
Get high performance http requests with fork process (forker inspired prefork feature in web servers)
prefork is a solution which is also used by other webservers
A server instance is opened for each processor core and incoming requests are shared between these instances
In order to distribute the load more evenly and handle more requests per second, there is a master that starts by the user, which then starts child processes on the other processor cores based on configuration
memory between the different processes is not shared, beacuse goroutines are independent processes
how to install
go get -u github.com/Ja7ad/forker
forker benchmark
