I was trying to perform apache benchmark on one of the server. However, the apache benchmark will always getting a timeout error.

I was wondering is there a module (like mod security) or a setting (like firewall) that blocking this?

curl is fine.

ab command:

ab -n 10 -c 10

from my local network, results:

Benchmarking (be patient)...Send request failed! apr_poll: The timeout specified has expired (70007) Total of 1 requests completed

from another server in the same network with the server I want to benchmark:

apr_poll: The timeout specified has expired (70007)
