haskell@gentoo.org Gentoo Haskell Use ByteString Builders to construct ByteString outputs instead of the ByteString type itself. If you're regularly constructing large (>50KB) bytestrings, enabling this can speed up your code. Otherwise, enabling this is likely to be a net slowdown. Enable benchmarks for Interpolation and interpolatedstring-perl6 Use Text Builders to construct Text outputs instead of the Text type itself. If you're regularly constructing large (>50KB) text objects, enabling this can speed up your code.
