Ticket #34 (closed defect: worksforme)
Performance with Immutable Boxed Vectors much worse in 0.6.0.x as compared to 0.5
|Reported by:||anonymous||Owned by:|
Performance with immutable boxed vectors from Data.Vector is approx 5-10x slower in version 0.6.0.x than it is/was in version 0.5. As result, I've been compiling with the older version of vector when using immutable boxed vectors. In contrast, I do see a nice performance improvement with unboxed vectors when going from 0.5 to 0.6.0.x. I didn't attach any code showing the problem, as it should be apparent with any benchmark you already have using immutable boxed vectors from Data.Vector.
