------------------------------------
Summary: VIntCoding should read and write more efficiently
Key: CASSANDRA-15215
URL: https://issues.apache.org/jira/browse/CASSANDRA-15215
Project: Cassandra
Issue Type: Bug
Components: Local/Compaction, Local/SSTable
Reporter: Benedict
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.
