User Comments:
GUEST: just trying to download the maven repo version of a jar.. netbeans was performing a "Scanning projects" task in the background..

In order to improve user experience tasks need to have a priority and the ones required by the user should always have precedence over netbeans-initiated tasks, otherwise it becomes very frustrating..



Maximum slowness yet reported was 79404 ms, average is 41771

another interesting segment of the stacktrace is how profiles are collected and how the maven project building code nests. Probably a feature of the project structure in question.
