Todd Lipcon created HDFS-3528:
---------------------------------
Summary: Use native CRC32 in DFS write path
Key: HDFS-3528
URL: https://issues.apache.org/jira/browse/HDFS-3528
Project: Hadoop HDFS
Issue Type: Improvement
Components: data-node, hdfs client, performance
Affects Versions: 2.0.0-alpha
Reporter: Todd Lipcon
Assignee: Todd Lipcon
HDFS-2080 improved the CPU efficiency of the read path by using native
SSE-enabled code for CRC verification. Benchmarks of the write path show that
it's often CPU bound by checksums as well, so we should make the same
improvement there.
