Basic Benchmark

Logic of the Benchmark

The benchmark is to identify a unit of scanning for a project. That unit is based on the following specifications and API is used to execute the scan to measure the operations precisely:

• 100 files
• 10,000 lines of code
• The default Java rule set
• 10 scans are run in one batch.
  • The first time the scan is executed, the Java rule set is loaded
  • the next 9 runs do not need to load the Java rule set and hence perform better.
• 3 batches of 10 scans each are run
  • On the first batch, the system must connect to Globalyzer, get the meta-data, etc., which lowers the performance
  • On the subsequent batches, the connection is established, and the first scan only reloads the rule sets as mentioned above.

If you have, say, 100,000 lines of code, on the system specified, it would about take 10 times the duration of this test.

If you have, say, two rule sets, it would take about twice the duration of this test.
