Re^2: Benchmarking Perl's Net::Async::FastCGI app consistently return LOTS of "Non-2xx responses"

[Anonymous Monk]

I already tried reducing both the number of total requests to 40, and concurrent requests to 20; and it still returns 24 "Bad Gateway"s. Since a concurrent requests level of 20 is really child-play, there's something very funky going on here. Using TCP port number instead of Unix socket makes it even worse. I literally use the helloworld example verbatum (except for the Unix socket tweak) from the Net::Async::FastCGI examples on metacpan.org. So kinda of run out of idea here...

Maybe try reducing the concurrency to 1 and 2, just to see if you are at all able to have more than one request in flight at the same time?

From ApacheBench result above, 15 out of 100 requests return a successful 200 OK code, while 85 of them return the 502 Bad Gateway.
