Public bug reported: Horizon Liberty
User reports slowness of the dashboard for most of the tabs. Investigation shows that Horizon makes duplicated requests when it is trying to request information related to the networking. It also waits for about 4 seconds right after the initial user's successfull authentication before it proceeds with the first API call. Here is the log of Horizon representing the delay: 2016-06-15 18:24:16,385 113992 DEBUG openstack_auth.backend Beginning user authentication 2016-06-15 18:24:16,387 113992 DEBUG openstack_auth.plugin.password Attempting to authenticate for admin 2016-06-15 18:24:16,387 113992 DEBUG keystoneclient.auth.identity.v3.base Making authentication request to http://192.168.210.69:5000/v3/auth/tokens 2016-06-15 18:24:16,481 113992 DEBUG keystoneclient.session REQ: curl -g -i --insecure -X GET http://192.168.210.69:5000/v3/ -H "Accept: application/j son" -H "User-Agent: python-keystoneclient" 2016-06-15 18:24:16,503 113992 DEBUG keystoneclient.session RESP: [200] content-length: 253 vary: X-Auth-Token server: Apache connection: close date: Wed, 15 Jun 2016 18:24:16 GMT content-type: application/json x-openstack-request-id: req-258d4e76-6500-414d-a565-0788dc0d4f90 RESP BODY: {"version": {"status": "stable", "updated": "2015-03-30T00:00:00Z", "media-types": [{"base": "application/json", "type": "application/vnd.o penstack.identity-v3+json"}], "id": "v3.4", "links": [{"href": "http://192.168.210.69:5000/v3/", "rel": "self"}]}} 2016-06-15 18:24:16,503 113992 DEBUG keystoneclient.session REQ: curl -g -i --insecure -X GET http://192.168.210.69:5000/v3/users/51e3873fe48f4948bef2 32865c7bc84f/projects -H "User-Agent: python-keystoneclient" -H "Accept: application/json" -H "X-Auth-Token: {SHA1}561e3b22c0693b6ff8dfad099a2492d95ed 8e9c1" 2016-06-15 18:24:16,561 113992 DEBUG keystoneclient.session RESP: [200] content-length: 412 vary: X-Auth-Token server: Apache connection: close date: Wed, 15 Jun 2016 18:24:16 GMT content-type: application/json x-openstack-request-id: req-765b3844-feb3-40b9-a843-f5cc2341afde RESP BODY: {"links": {"self": "http://192.168.210.69:5000/v3/users/51e3873fe48f4948bef232865c7bc84f/projects", "previous": null, "next": null}, "proje cts": [{"is_domain": false, "description": "admin tenant", "links": {"self": "http://192.168.210.69:5000/v3/projects/49cdffc876ca4927af2ea7505ad27264" }, "enabled": true, "id": "49cdffc876ca4927af2ea7505ad27264", "parent_id": null, "domain_id": "default", "name": "admin"}]} 2016-06-15 18:24:16,561 113992 DEBUG keystoneclient.auth.identity.v3.base Making authentication request to http://192.168.210.69:5000/v3/auth/tokens 2016-06-15 18:24:16,657 113992 DEBUG openstack_auth.backend Authentication completed. 2016-06-15 18:24:16,657 113992 INFO openstack_auth.forms Login successful for user "admin". 2016-06-15 18:24:20,167 113996 DEBUG neutronclient.client REQ: curl -i https://domain.com:9696/v2.0/extensions.json -X GET -H "User-Agent: pyt hon-neutronclient" -H "X-Auth-Token: {SHA1}04486c34b57ca19787b77e6d5e6e9fad48914b67" Last 2 rows represent the issue.
