This project exists purely for research purposes of determining the optimal way of building strict bytestrings. The ideas behind this project stem from a discussion on Reddit.
If you know any way of optimizing any particular benchmark or can suggest another benchmark subject, instead of complaining, PR without hesitation! This is intended to be a community project.
ByteString.TreeBuilder is the clear winner. With the standard and "blaze" builders being at least 4 times slower on all input sizes.
