>                 Key: STORM-241

>             Project: Apache Storm
>          Issue Type: Improvement
>          Components: storm-core
>         Environment: Internet connected dev machine deploying to storm cluster on AWS.  Storm 0.9.0.1
>            Reporter: Adam Lewis
>            Assignee: Adam Lewis
>              Labels: configuration, newbie
>             Fix For: 0.9.2-incubating

>
> "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
