httperf always get "Connection refused" (MacOS)

  • 772

I want to use httperf as a benchmark tool for developing RubyOnRails site. But it always gets "Connection refused" and I have no idea why.

12:24 $ httperf localhost --port=3000 -v -d10
httperf --verbose --client=0/1 --server=localhost --port=3000 --uri=/ --send-buffer=4096 --recv-buffer=16384 --ssl-protocol=auto --num-conns=1 --num-calls=1

What I am possibly doing wrong? System is MacOS 10.8.5, httperf is built from source.

12:39 $ httperf --verbose --version
httperf: httperf-0.9.1 compiled Feb  9 2016 with DEBUG without TIME_SYSCALLS.

Update: siege gets "Connection refused" as well:

  1. Seems that problem was in 'localhost' - everything works if I use 127.0.0.1.
