--------------------------------

             Summary: "storm jar" underperforms compared to scp
                 Key: STORM-241
                 URL: https://issues.apache.org/jira/browse/STORM-241
             Project: Apache Storm (Incubating)
          Issue Type: Improvement
         Environment: Internet connected dev machine deploying to storm cluster on AWS.  Storm
0.9.0.1
            Reporter: Adam Lewis


"storm jar" is very slow at sending the jar file, achieving roughly 10% of the throughput
compared to SCP for the same network configuration.  This is especially problematic when deploying
jars from over the Internet.

This appears to be related to the chunk size used to transmit the JAR file over the thrift
protocol.  Anecdotally, a 300KB chunk size (compared to the currently used default of 15KB),
achieved performance in line with scp.

Default can be overridden in the BufferFileInputStream ctor: https://github.com/apache/incubator-storm/blob/master/storm-core/src/jvm/backtype/storm/StormSubmitter.java?source=cc#L154
