--------------------------------
Summary: Provide more efficient implementations of the local and
content repositories.
Key: ARIES-1394
URL: https://issues.apache.org/jira/browse/ARIES-1394
Project: Aries
Issue Type: Improvement
Components: Subsystem
Affects Versions: subsystem-2.0.2
Reporter: John Ross
Assignee: John Ross
These measurements use a new test scenario to help flush out bottlenecks in the
local and content repositories. The time it took to install 1 application was
measured. The application consisted of 200 bundles. Half of the bundles each
exported 50 packages. Half of the bundles each imported 50 packages. This gives
a total of 5000 requirements and 5000 capabilities.
Before
Average time across 1 trials: 13915.0 ms
Average time across 1 trials: 14628.0 ms
Average time across 1 trials: 14196.0 ms
Average time across 1 trials: 13905.0 ms

After
Average time across 1 trials: 7781.0 ms
Average time across 1 trials: 7782.0 ms
Average time across 1 trials: 8085.0 ms

A 44.2% overall improvement.
Before, obtaining the subsystem region took 2254 ms, or 14.4%. After caching
the region context bundle and using it to perform the region lookup, the effort
no longer registered on a profiler with a 50 ms sampling period.
Before, finding providers from the local repository took 2260 ms, or 15.3%.
After adding the capability set, it took 747 ms, or 5.9%.
Before, asking whether or not a resource was content took 2152 ms, or 16.9%.
After answering by using existing content resource sets rather than the content
header, the effort no longer registered on a profiler with a 50 ms sampling
period.
Before, finding providers from the content repository took 4510 ms, or 28.8%.
After adding the capability set, it took 49 ms, or 0.4%.
