Mike Beckerle updated DAFFODIL-2706:
------------------------------------
Priority: Minor (was: Major)
> Memory size limits - measurements needed - doc online should publish it
> -----------------------------------------------------------------------
>
> Key: DAFFODIL-2706
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2706
> Project: Daffodil
> Issue Type: Bug
> Components: Documentation, QA
> Affects Versions: 3.3.0
> Reporter: Mike Beckerle
> Priority: Minor
> Labels: beginner
>
> (Categorized this as a bug, because this is not a measurement we are making
> and talking about in our documentation)
> Users have requested information about how small a JVM memory footprint can
> run Daffodil, assuming loading of a precompiled DFDL schema.
> We should have such a test for Runtime 1, and the results should be published
> for each release.
> This is of course somewhat schema dependent. That is a schema for large
> messages which cannot be streamed for unparsing will have large footprint no
> matter what. I think the interest is for small message data - e.g. data that
> is typical messages up to 1Kbyte in size.
> The test needs to scrutinize time spent in Java Garbage Collection overhead,
> as the memory should not be so small as to drive up the GC overhead level.
> The interest comes from wanting to run Daffodil on devices using smaller CPUs
> such as are found in embedded devices, phones, gateways, etc. (ARM and Atom
> CPUs typically)
