> More investigation is required to understand where the difference comes from. After playing a bit more with the benchmark, it looks like 1ns is coming from the various alignment checks we need to perform - whereas ~0.5ns is coming from the segment liveness check. Of course, since this is a single call, the cost for these checks cannot be amortized. We can probably improve things a little (esp. when there's no alignment involved), but the numbers above reflect the fact that the memory segment implementation has more checks, so at the nanosecond scale, everything matters of course. -- This is an automated message from the Apache Git Service.
