>
> The performance of profile builder used by karaf maven plugin has reduced
> significantly in 4.1 compared to 4.0.
> The java streams API is being used in 4.1 to filter our the required features
> from the set of all features present in the repositories that are part of the
> profile. This is done in the "addFeatures" method in the "Builder.java" class
> in the "org.apache.karaf.profile.core" bundle. This change (from 4.0) has
> drastically reduced the performance. For a profile with ~900 features in all
> the repositories in the profile and ~300 required features from a highly
> complex feature dependency tree, this function is taking around 13min to
> complete. The same execution took around 3-5min in 4.0 (where simple for
> loops were being used).
