> 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.
