Port performance patches from private bytestring branch
- simplify chunk insertion (strict bytestrings instead of
lazy-byestring-continuations)
- bytestring chunk insertion is half as fast as on blaze-builder. This
performance loss can be attributed completely to the change from using
'inlinePerformIO' to using 'unsafePerformIO' in the conversion from
builders
to lazy bytestrings. This slowdown can be circumvented by executing
buildersin the IO monad, where no unsafePerformIO is necessary.
- rewrite some of the primitive builders to a non-recursive form to avoid
unnecessary closure allocation on the fast path
