-----------------------------------------------------------------
Do you understand what caused your "dramatically decrease application
performance"?
Have you confirmed that changing it to be at the region level dramatically
improved performance?
I think it is possible that when read conflicts are detected it could cause
concurrent transactions that read the same entry to fail with a conflict
exception even though the entry was never written. If this is true then that
would be a bug and should be fixed even if this feature request does not happen.

> Geode supports detect read conflict(-Dgemfire.detectReadConflicts=true) on
> transaction commit(see
> https://geode.apache.org/docs/guide/11/developing/transactions/transaction_semantics.html)
> This functionality can be enabled only on application level. It can
> dramatically decrease application performance.
> I propose to add ability to setup this property per region basis.
