Subject [jira] [Created] (HDFS-4498) Investigate possible performance benefits by using protobuf option optimize_for = SPEED
Date Wed, 13 Feb 2013 18:58:13 GMT
Ravi Prakash created HDFS-4498:
----------------------------------

             Summary: Investigate possible performance benefits by using protobuf option optimize_for
= SPEED 
                 Key: HDFS-4498
                 URL: https://issues.apache.org/jira/browse/HDFS-4498
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 3.0.0, 2.0.3-alpha, 0.23.6
            Reporter: Ravi Prakash


The default is to optimize for code size : https://groups.google.com/forum/?fromgroups=#!topic/protobuf/OtL7Bb4NiRI

Has anyone ever investigated how much effort protobuf de/serialization takes and whether it
would make a difference if we used this option? In benchmarks, the options seems to make a
huge difference:

I don't plan to take this up, so if anybody else does, please feel free
