> sys 1m23.629s
> [https://github.com/opendaylight/integration-distribution/tree/master/features/repos/index]
> takes ~638 seconds to generate:
> real 10m38.859s
> user 7m55.004s
> sys 3m17.269s
> Running profiling shows that this time is dominated by short-lived
> FileInputStreams being generated at a rate of 7K-8Kps – which are coming from
> both feature reading and from artifact resolution.
