> Measure tuple serialization/deserialization latency.

> Key: STORM-671
> URL: https://issues.apache.org/jira/browse/STORM-671
> Project: Apache Storm
> Issue Type: New Feature
> Reporter: Robert Joseph Evans
> Assignee: Kai Sasaki
>
> Some times the serialization/deserialization cost can be very high, and it is
> not currently measured anywhere in storm. We should measure it, at least in
> a similar way to how we do execute and process latency.
