Mike Beckerle commented on DAFFODIL-2627:
-----------------------------------------
Simplest thing is just add a runner flag, which we could set in runners for
projects like P8. The flag would tell it that the compiled schemas should never
be reclaimed. So in addition to adding them to the weak hash map, it would add
them to some singleton list.
Most DFDL schema projects would set this flag. Apache Daffodil itself would
not.

> Key: DAFFODIL-2627
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2627
> Project: Daffodil
> Issue Type: Bug
> Components: TDML Runner
> Affects Versions: 3.2.0
> Reporter: Josh Adams
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 3.3.0
>
>
> While working on a customer project we noticed a significant increase in the
> amount of time it took to run our test suit (over 600 tests) after upgrading
> from Daffodil 2.7.0 to 3.2.1. We were seeing roughly a 4x increase in time
> to complete the same set of tests.
> I've narrowed the performance regression to commit
> 0700ee8dc9531497f3e8b0fdf9266f8e3b105c27 which involved a removal of the
> schema compilation cache, which is likely causing the schema to need to be
> recompile much more frequently.
> We use a relatively large schema (over 10,000 lines), but it is the same
> schema used for all tests.
