Nowhere. Use the WordPress memcached plugin at 
http://wordpress.org/extend/plugins/memcached/ and it will do the work 
for you. Do make certain that you have memcached installed (and running) 
as well as the PECL-memcache PHP extension. See http://memcached.org/ 
and http://pecl.php.net/package/memcache.

BTW, if you really want efficiency for your site, and since you're 
asking about using memcached it seems that you are, you should rewrite 
the config to get rid of the if's, and use locations and try_files 
instead. See http://wiki.nginx.org/IfIsEvil.

A more efficient config might be (not tested so YMMV):

server{
         listen 80;
         server_name www.mywebsite.com;
         access_log /var/log/nginx/mywpt.access_log;
         error_log /var/log/nginx/mywpt.error_log;

		root /home/mywebsite/public_html;

	#will capture most static files and serve them. Add other types if you 
need to

         location ~* \.(gif|jpg|jpeg|png|css|js|ico)$ {
	   expires 30d;
	}
		
         location / {
           root /home/mywebsite/public_html/;
           index index.html index.htm index.php;

           # this will capture and serve any other static file types 
missed above and send the rest to your fallback rewrite
           try_files $uri $uri/ /index.php?q=$request_uri;
	}


         location ~ \.php$ {
             fastcgi_pass    127.0.0.1:9000;
             fastcgi_index   index.php;
             fastcgi_param   SCRIPT_FILENAME
/home/mywebsite/public_html/$fastcgi_script_name;
             include         fastcgi_params;
         }
		
}
