Bas updated ARIES-1357:
-----------------------
Attachment: PreferredProviderIsEqual.patch
The preferred provider repository should be able to compare resources
originating from different locations. For example one from an obr repository
and one that is already installed. So using the ResourceHelper.areEqual is
required here.
Using this patch I was able to install our subsystems while using revision
1701286 of 2.0.3-SNAPSHOT.
> BasicSubsystem can be used by the subsystem install process a factor 6 times
> faster

> The problem was poor performance while installing a subsystem on a container
> with 200+ subsystems installed.
> While doing performance analyses on the subsystem install process we noticed
> the BasicSubsystem is working a lot with its manifest instead of
> pre-calculating data that is used a lot.
> While using the pre-patch version of BasicSubsystem a subsystem install
> (while having 200+ running subsystems) could take more than a minute. While
> using the patched version where we pre-calculate highly used data when a new
> subsystem manifest or deployment manifest is set we could bring it down to 10
> seconds. We only pre-calculated the data that was highly used.
