--------------------------------------
Summary: HFile performance regression 92/94
Key: HBASE-7868
URL: https://issues.apache.org/jira/browse/HBASE-7868
Project: HBase
Issue Type: Bug
Components: io
Affects Versions: 0.94.5
Reporter: Matteo Bertozzi
Assignee: Matteo Bertozzi
By HFilePerformanceEvaluation seems that 0.94 is slower then 0.92
Looking at the profiler seems that most of the time, compared to 92, is spent
in the metrics dictionary lookup. [~eclark] pointed out the new per
family/block metrics.
By commenting the metrics call in HFileReaderV2, the performance seems to get
better, but maybe metrics is not the only problem.
