Description Erno Mononen 2009-10-15 14:34:48 UTC 
In the attached snapshot TaskIndexer#index takes 29s for a single Rails project. If it can't be made much faster than 
that, it should probably be turned off by default (at least for Ruby/Rails projects where the initial scanning of gems 
takes also a long time). The snapshot was taken when opening the OneBody project, git://github.com/seven1m/onebody.git 
(if you want to try it, checkout and create a new rails app w/ existing sources for it).

Comment 2 Stanislav Aubrecht 2009-10-27 14:06:34 UTC 
the snapshot shows that org.netbeans.ruby.railsprojects.RailsSource.getSourceGroups() is slow and it is invoked for each
file the task list needs to process. perhaps some weak-caching might speed it up a bit...
reassigning to ruby team for evaluation
