Koushik Das commented on CLOUDSTACK-4179:
-----------------------------------------
Yes that's right. The looping through all the resources needs to be eliminated
by offloading to the db. I will look at the query. Also one more thing, do you
know why the dedicated resource check is done twice for a single VM deployment?
> [Performance Testing] Time taken for Deploy VM async job to complete is
> considerably higher

> Key: CLOUDSTACK-4179
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4179
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.2.0
> Environment: Simulated VMs and hosts, advanced zone, RVR
> Reporter: Sowmya Krishnan
> Assignee: Koushik Das
> Priority: Critical
> Fix For: 4.2.0
>
> Attachments: async_job_time.out, job-109.log

> Following setup is used to create performance test bed:
> Advanced zone, 2 Management Servers, 124 Pods [Each Pod having 2 Clusters]
> 248 Clusters [Each cluster having 8 hosts and one primary storage]
> 2000 Hosts
> 4000 User accounts [Each account having one network]
> ~8000 Virtual Routers
> Following config parameters were used in both the management servers
> - Java heap size = 5 GB
> - db.cloud.maxActive = 250
> -
> db.cloud.url.params=prepStmtCacheSize=517&cachePrepStmts=true&prepStmtCacheSqlLimit=4096&includeInnodbStatusInDeadlockExceptions=true&logSlowQueries=true
> Tried deploying around 4000 Simulator VMs across 4K accounts. Noticing
> considerably higher time for deploy VM async job to complete as compared to
> baseline results.
> Some of the Baseline results are documented here:
> https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baseline+Reports+for+Pre-4.x+Performance+Runs
> On an average, it is now taking 70-80 seconds for deployVM to complete as
> compared to 10-15 seconds earlier.
> From the logs, it appears in some cases, DeploymentPlanningManager takes time
> to kick in.:
