Derek Dagit commented on STORM-241:
-----------------------------------
I am +1 on the patch. Good discussion.
> "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
> Labels: configuration, newbie
>
> "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:
