Michael Miller updated DAFFODIL-2222:
-------------------------------------
Priority: Minor (was: Major)
> InfosetInputter cached DaffodilTunables
> ---------------------------------------
>
> Key: DAFFODIL-2222
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2222
> Project: Daffodil
> Issue Type: Bug
> Components: Performance
> Affects Versions: 2.4.0
> Reporter: Michael Miller
> Priority: Minor
>
> Is it possible to allow the {{InfosetInputter,}} and subclasses, to have a
> {{DaffodilTunables}} object pre-created passed into its constructor?
> When profiling unparse performance, some class/resource loaders do not handle
> the {{DaffodilTunables}} initialization very well. In particular, if your
> using a container like Wildfly, the ModuleClassLoader is very inefficient,
> and hits disk io heavily, during the \{{getResource("/daffodil-config.xml")}}
> that happens for every single {{InfoSetInputter}} construction.
> Is it necessary to have a newly generated {{DaffodilTunables}} everytime an
> unparse is called?
> If the above is not possible, is there a way to reuse {{InfosetInputter}}
> objects and reset them for repeated calls to avoid the {{new
> DaffodilTunables()}} overhead?
