-------------------------------------------
Summary: [Performance Testing] Adding hosts take much longer time
than baselines
Key: CLOUDSTACK-4350
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4350
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: 4.2, performance test env, with simulator
Reporter: Sowmya Krishnan
Priority: Critical
Fix For: 4.2.0
Performance test setup:
Basic zone, 1 host/cluster, tyring to deploy 20K simulator Hosts, with host tags
Compared to baseline numbers, deploying hosts is taking much longer in the
simulator environment
For the 1st 1000 hosts, it took about 4 mins to deploy as per baseline
With 4.2, the 1st 1000 hosts are taking almost 7 minutes
Configurations:
heap size: -Xmx12288m
db.cloud.url.params=prepStmtCacheSize=517&cachePrepStmts=true&prepStmtCacheSqlLimit=4096&includeInnodbStatusInDeadlockExceptions=true&logSlowQueries=true
For 20K Hosts, the number exponentially increases and the deployment time also
increases.
Attaching trace logs of 4.2 for 1k simulator hosts deployment.
