From Revision 5847.1.6 to 5834

Rev	Summary	Authors	Date
5847.1.6	Document the split_dirs reason. Document the split_dirs reason. Shave another 3-500ms off by turning more tuples into StaticTuples. Direct times with a pre-warmed RevisionTree is ~2.4s down to 2.0s for set_parent_trees().	John Arbash Meinel	13 years ago
5847.1.5	We don't need a second named parameter. We don't need a second named parameter. .from_sequence is only called for each new dir (about 4k times), vs for every file (70k times). So it isn't an expensive lookup. The big thing is to just use StaticTuple, and make it not too expensive to access it.	John Arbash Meinel	13 years ago

Using StaticTuple as the primary object has a surprising benefit. Drops us from ~700ms down to 400ms. My guess is the 65k tuples were causing us to hit a minor gc run, and putting StaticTuple instead is avoiding it.	John Arbash Meinel	13 years ago
5847.1.2	using tuple() is consistently slower. Save ~100ms more. using tuple() is consistently slower. Save ~100ms more. I'm guessing it happens enough that the overhead of calling tuple() costs more than the benefit of not having lists.	John Arbash Meinel	13 years ago
5847.1.1	DirState._sort_entries was showing up for 'uncommit' times. DirState._sort_entries was showing up for 'uncommit' times. This shaves a consistent 500ms off of 'uncommit' (from 15.6s to 15.1s) in a 70k-entry tree. Basically, we cache the results of path.split('/') rather than re-doing it for every file in every directory. I tried implementing it via a cmp() function, to avoid split entirely (since we have cmp_by_dirs). That seemed to make it significantly slower, probably because of cmp() call overhead vs key. Small win, but small change.	John Arbash Meinel	13 years ago
