Edit: I found the answer to the problem described below was to use 127.0.0.1 rather than localhost (on MacOS).

I got the same results: 

Concurrency Level:      50
Time taken for tests:   0.040 seconds
Complete requests:      100
Failed requests:        0
Non-2xx responses:      57
Total transferred:      44998 bytes
HTML transferred:       28931 bytes
Requests per second:    2507.33 [#/sec] (mean)

The Non-2xx responses were 502s.

I tried fiddling with the proxy settings, but it made no difference.

Hope this helps.

Original comment:

More instructions needed. The fastcgi script is serving the /helloworld content when I use curl -L (it's returning a 301), but when I use Apache Bench I get apr_socket_connect(): Invalid argument (22). There's also no file at /tmp/myUDS.sock (which is where I configured it in nginx conf and in the Async script).


The way forward always starts with a minimal test.
