34000 requests per second on a modest laptop

Here's a video showing how to create and start an application server, and how to connect to it and make requests from a C client (or from any language that supports C API extension):

Create new directory for the Golf server and also for C API client:
mkdir -p srv-example
cd srv-example
mkdir -p client

Create file "srv.golf" and copy this:
 begin-handler /srv public
     silent-header
     @Hello world!
 end-handler

Create Golf application server:
gg -k hello

Start the application server (a single-process server in this case):
mgrg -w 1 hello

Next, go to C API client directory:
cd client

Then create C file "cli.c" and copy this:
 #include "gcli.h"

 int golf_client (gg_cli *req, char *connection, char *method, char *app_path, char *request, char *url_params);

 int golf_client (gg_cli *req, char *connection, char *method, char *app_path, char *request, char *url_params)
 {
     memset ((char*)req, 0, sizeof(gg_cli));
     req->server = connection;
     req->req_method = method;
     req->app_path = app_path;
     req->req = request;
     req->url_params = url_params;
     return gg_cli_request (req);
 }

 void main ()
 {
     int i;
     for (i = 0; i < 100000; i++)
     {
         gg_cli req;
         int res = golf_client (&req, "/var/lib/gg/hello/sock/sock", "GET", "/hello", "/srv", "/");
         if (res != GG_OKAY) printf("Request failed [%d] [%s]\n", res, req.errm);
         else printf("%s", gg_cli_data(&req));
         gg_cli_delete(&req);
     }
 }

Compile the client:
gcc -o cli cli.c $(gg -i) -O3

Run it:
./cli

The result is "Hello world!" 1,000,000 times from each request invocation.
