I work with a project that contains tens of thousands of classes that span about 3m lines of code. Jump to any symbol responds to a fuzzy search in about one second. Jump to class autocompletes instantly as I type, and a rename takes a few seconds to update all classes in the project, including references from xml files and comments.
