> Project: Karaf
> Issue Type: Improvement
> Components: karaf-instance
> Affects Versions: 3.0.1, 2.3.5
> Reporter: Freeman Fang
> Assignee: Freeman Fang

>
> For an instance, admin:list will write underlying cfg file 9 times for each
> instance, that said, if we have 3 child instance with 1 root instance,
> "admin:list" will cause 36 times file write which is a significant
> performance lost as well as more chance to corrupt the cfg file.
> For some operations in AdminService like get***Port, getInstance, getStatus,
> which are read-only operations, we should avoid writing back to the cfg file
> after read
