Thanks for the reminder! I’ll make note of that. In these tests the clients are hitting Nginx (which is acting as a load balancer) so I could try disabling keep-alive there and seeing what happens. So far I just used the default that was written into the conf when the package was installed ("keepalive_timeout 65;”).
FWIW, I started an etherpad to track a shortlist of ideas: https://etherpad.openstack.org/p/zaqar-performance-testing On 9/16/14, 11:58 AM, "Jay Pipes" <jaypi...@gmail.com> wrote: >On 09/16/2014 11:23 AM, Kurt Griffiths wrote: >> Hi crew, as promised I’ve continued to work through the performance test >> plan.
