Description

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%.
