"Execute decorators" phase takes forever

I was just analyzing our (1 main/ 3 sub) project and wanted to analyze the code with my local Sonar server by typing mvn sonar:sonar (after cleaning and packaging the project(s)).

It successfu开发者_StackOverflow社区lly analyzes the EJB project but in the phase Execute decorators ... it takes forever to complete (around half an hour). This makes the analysis of the project very slow. What is going on in that phase and how can I improve the speed?

Best regards, Sebastian

Versions used:

• Maven 3.0.3
• Sonar 2.10

According to this, it could be linked to using Derby, the only proposed solution is using a stronger db instead.

Following comments from sinbadblue here are links to discussions with answers from sonar team members which suggest 2 known reasons for execute decorator to be slow :

• Using derby
• Having the database server on a different network from the analyzer

Here are the links

The database is not always the issue but these 2 should definitely be checked before further investigation.
