[forge-issues] [JBoss JIRA] (FORGE-2201) Fetch all Projects is very slow (>2 mins)

[George Gastaldi (JIRA)]

    [ https://issues.jboss.org/browse/FORGE-2201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13037396#comment-13037396 ] 

George Gastaldi commented on FORGE-2201:
----------------------------------------

You can use {{ProjectFactory.containsProject()}} instead, and then call findProject later.
Even though we do cache the projects, your code may be slow when run under 30 projects because of the facet installation detection algorithm, hence that's why we recommend using findProject only when you need to use the Project

> I want to fetch all available projects. The following source works as needed but needs at least 2 mins until completed (about 30 projects): 
> 	protected void setupProjects(UIBuilder builder) {
> 		Project entityProject = getSelectedProject(builder.getUIContext());
> 		Resource<?> resource = entityProject.getRoot().getParent();
> 		allProjects = new HashSet<>();
> 		for (Resource<?> res : resource.listResources()) {
> 			DirectoryResource directory = (DirectoryResource) res.reify(DirectoryResource.class);
> 			if (directory != null) {
> 				Project proj = projectFactory.findProject(directory);
> 				if (proj != null) {
> 					allProjects.add(proj);
> 				}
> 			}
> 		}
> 	}
> Is there a faster way to iterate through the projects or maybe some initialization can be done by "lazy loading"?
