[httperf] Server response hangs until timeout

[Tom]

Hi

I am looking into using httperf to profile the Openstack API server.

I have been able to run httperf on an (over) simplified ping-pong 
example but run into problems hen a GET request is run against the API 
server itself.

httperf --server x.x.x.x --port=8774 --client=0/1 --uri 
/v1.1/myproject/servers/detail?fresh=1329234243.33 --hog --method GET 
--add-header "X-Auth-Project-Id: myproject\nUser-Agent: 
python-novaclient\nX-Auth-Token: XXXXXXXXXXX" --rate 1 --num-conns=1 
--timeout=5 --num-calls=1 --recv-buffer=4096 --verbose

Tailing the logs I see the request gets processed by the server, but 
only after the timeout is breached.

Hence I get the reported Errors:

Errors: total 1 client-timo 1 socket-timo 0 connrefused 0 connreset 0

Similarly Wireshark shows the GET request immediately but the reply 
doesn't show until after the timeout.

Thanks for your help

Tom
