Cloning the vector of Buffers and child ArrayData has some overhead. Incrementing the reference counts should be relatively cheap unless there are concurrent threads accessing the same Arc. I tried replacing the vectors inside ArrayData with SmallVec some time ago. That made the slice benchmarks faster, but several other benchmarks slowed down because of it. Might be worth to revisit that. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
