Description

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%.
