A question of fastcgi_pass method

I'm a chinese ,sorry for my poor english.
I'm new to nginx. I have installed nginx 0.7.67 ,and installed flup
,web.py to use python .
I writer a simple test.py file ,and just run : python test.py . VIsit
http://ip:8080 and it works well.
That means the web.py is right installed.
So, I try to use nginx with this python file.
I edit the nginx.conf like this:
fastcgi_param SERVER_NAME $server_name;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
and use spawn-fcgi to start up the python file :
spawn-fcgi -f FILE -a 127.0.0.1 -p 9000
then visit the address http://ip it works ,shows the result what I wanted
and then I simply change the fastcgi_pass method TCP to UNIX SOCKET
nginx.conf : fastcgi_pass unix:/tmp/nginx.socket
spawn-fcgi command : spawn-fcgi -f FILE -s /tmp/nginx.socket ( And change
the mod of /tmp/nginx.socket to 777 ).
This times it works well too .
Then I just did a simple test for this two different way of connections
between nginx and spawn-fcgi .
I use webbench to do this test : webbench -c 100 http://IP/
This is the result:
USE TCP Method:
Speed=5730 pages/min, 14038 bytes/sec.
Requests: 2865 susceed, 0 failed.
USE UNIX SOCKET Method:
Speed=5548 pages/min, 13592 bytes/sec.
Requests: 2774 susceed, 0 failed.
Why the test shows that TCP method is faster than Unix Socket ?
And an other quertion is :during the TCP Method test ,I typed : netstat -an
| grep 9000 ,this were many ports shows
TIME WAIT .almost over 3,000 . when the webbench is over ,zhe TIME WAIT
ports number is decrease.
Why this ,And is it safe ?
