Sowmya Krishnan commented on CLOUDSTACK-4158:
---------------------------------------------
The test bed used are exactly the same as those used for 4.1. So also the
configuration parameters.
> [Performance Testing] List API performance in comparison to 4.1 is not as good

> Key: CLOUDSTACK-4158
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4158
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the

> Components: API
> Affects Versions: 4.2.0
> Environment: Simulator for creating mock resources, advanced zone, RVR
> Reporter: Sowmya Krishnan
> Priority: Critical
> Fix For: 4.2.0
>
>
> Executed few List API calls for tracking performance runs for 4.2 and
> compared the results with 4.1. Most APIs are taking noticeably longer as
> compared to 4.1
> Examples:
> API Time taken in 4.1 Time taken in 4.2
>
> listAccounts 1m25.348s 2m22.628s
> listEvents 0m6.575s 0m20.277s
> Results so far are posted here (including comparitive results)
> https://cwiki.apache.org/confluence/display/CLOUDSTACK/Performance+Test+Execution+for+4.2
> Performance Test bed details:
> =======================

> Operating System
> CentOS release 5.5 (Final), x86_64
> Configuration Parameters
> 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
> Setup:
> =====
> 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]
> 4000 User instances
> ~8000 Virtual Routers [Since we are using Redundant Virtual Router offering
> Didn't notice any slow queries logged in DB.
