Dev Build 3125 is out now at https://www.sublimetext.com/3dev
There are two indexing related changes in 3125:
There’s now an Indexing Status entry in the Help menu, which will show you exactly what’s going in with the indexer. This will give you the same information that
sublime.log_indexing(True)will have shown in the past, but without the hassle.
The default number of index workers has been reduced. In the past it was one worker per core, now it’s num_cores/2, unless you have more than 4 cores, in which case it’s num_cores - 1. While this will reduce indexing speed, it should also make it less intrusive. You can still set this explicitly with the index_workers setting.
