> Project: Aries
> Issue Type: Improvement

> These measurements use a more beefed up version of the test from ARIES-1394.
> The time it took to install 1 application was measured. The application
> consisted of 300 bundles. 200 of the bundles each exported 50 packages. 100
> of the bundles each imported 50 packages. This gives a total of 5000
> requirements and 10,000 capabilities. 100 of the exporting bundles serve as
> preferred providers.
> Before, calculating dependencies took 6728 ms, or 43.6%. After making use of
> the capability set, it took 2005 ms, or 18.2%.
> Baseline
> Average time across 1 trials: 13841.0 ms
> Average time across 1 trials: 13820.0 ms
> Average time across 1 trials: 13982.0 ms
