Sowmya Krishnan commented on CLOUDSTACK-4158: --------------------------------------------- I don't have TRACE enabled logs for 4.1. We didn't need it since we only saw improvement as compared to pre-optimization. I would need to re-build 4.1 to get those logs. Currently the set up is running 4.2 performance runs. I'll complete those and get to this if we plan to fix it for 4.2. > [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 > default.) > 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.
