>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15215
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Local/Compaction, Local/SSTable
>            Reporter: Benedict
>            Priority: Normal
>             Fix For: 3.0.x
> Most vints occupy significantly fewer than 8 bytes, and most buffers have >= 
> 8 bytes spare, in which case we can construct the relevant bytes in a 
> register and memcpy them to the correct position.  Since we read and write a 
> lot of vints, this waste is probably measurable, particularly during 
> compaction and flush, and can probably be considered a performance bug.
