Summary: X-link: facebookincubator/nimble#122 More than 10% of the CPU are spent on the destruction of local partition output when the load is high. Also add some optimizations for serialization. Optimization on `ByteOutputStream::appendOneBool` does not show significant gain in the query in example (because they are a lot small batches), but it is net gain and would be significant in large batches, so I leave it in the code.
