findFileName() && findFilePath() do not recursively search the project, they look at the HashMap.
However the collectFiles() method is call once and will traverse the project. But
this is done with a visitor, IResourceProxyVisitor. This mechanism is fast since the
workspace is partly cache.
Do you see any noticable slow down ?
