Can I close this ticket as not being to do with uvector? -- Don
You did notice the suggestion that performance of uvector and bytestring could be improved drastically if compile-time fusion would be augmented with runtime fusion?
The storablevector package implements Data.StorableVector.Lazy Just as with Data.ByteString.Lazy, it contains a linked list of chunks. I think that this can improve performances of my implementation, since it is much more efficient to append elements at the end of the vector (it avoids a lot of copying). In my draft implementation of the the Netflix Prize in D language, I used a similar implementation, base on: http://mdounin.ru/hg/nginx-vendor-current/file/tip/src/core/ngx_list.h Unfortunately, D garbage collector is really bad when there are a lot of allocations, so I gave up.
