Subject [jira] [Created] (CLOUDSTACK-596) DeployVM command takes a lot of time to return job id
Date Fri, 07 Dec 2012 12:23:21 GMT
Koushik Das created CLOUDSTACK-596:
--------------------------------------

             Summary: DeployVM command takes a lot of time to return job id
                 Key: CLOUDSTACK-596
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-596
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: pre-4.0.0, 4.0.0
            Reporter: Koushik Das
             Fix For: 4.0.1


This is a perf issue typically seen for larger deployments (advanced zone, user accounts ~4k,
lot of guest networks). The issue happens when deployVM is called without 'networkids' parameter.
In this case a search is done to identify the default guest network to use for deploying VM.
The search logic doesn't scale up for larger deployments resulting in delay in returning async
job id. 

Tests results showed that for ~4k user accounts and similar number of guest networks it takes
approx. 15 secs. to return async job id.
