Hi *, we're running Openstack on top of Leap 42.1. Since switching to Mitaka, we're experiencing severe delays when accessing the dashboard - i.e. switching between "Compute - Overview" and "Compute - Instances" takes 15+ seconds, even after multiple invocations. I've had a look at the requests, the Apache logs and our control node's stats and noticed that it's a single call that's taking all the time... I see no indications of any error, it seems that once WSGI is invoked, that call simply takes its time. Intermediate curl requests are logged, so I see it's doing its work. Looking at "vmstat" I can see that it's user space taking all the load (Apache / mod_wsgi drives its CPU to 100%, while other CPUs are idle - and no i/o wait, no system space etc.). Current test, switching to "Overview" took 13.09 secs loading http://control1/project/. Switching back to "Instances" took 14.7 secs for http://control1/project/instances/. Ain't no fun using the dashboard that way... and we did not see this with previous releases. Do others see the same slowness or is it likely some (system or Openstack) configuration issue on our side? Just for reference, we're running the following version of Horizon: --- cut here --- control1:/etc/apache2/conf.d # rpm -qi openstack-dashboard-9.0.1~a0~dev12-2.1.noarch Name : openstack-dashboard Version : 9.0.1~a0~dev12 Release : 2.1 Architecture: noarch Install Date: Tue May 10 12:39:04 2016 Group : Development/Languages/Python Size : 51400386 License : Apache-2.0 Signature : RSA/SHA256, Mon May 9 11:07:15 2016, Key ID 893a90dad85f9316 Source RPM : openstack-dashboard-9.0.1~a0~dev12-2.1.src.rpm Build Date : Mon May 9 11:06:31 2016 Build Host : build81 Relocations : (not relocatable) Vendor : obs://build.opensuse.org/Cloud:OpenStack URL : http://wiki.openstack.org/OpenStackDashboard --- cut here --- Regards, Jens -- To unsubscribe, e-mail: opensuse-cloud+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-cloud+owner@opensuse.org
