> These measurements use the same test as in ARIES-1396. 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, finding providers from the preferred provider repository took 3305
> ms, or 25.0%. After making use of the capability set, it took 948 ms, or 8.6%.
> Baseline
> Average time across 1 trials: 12974.0 ms
> Average time across 1 trials: 12597.0 ms
> Average time across 1 trials: 12760.0 ms
> Average time across 1 trials: 12573.0 ms
> Average time across 1 trials: 12339.0 ms
> 12648.6
