> Key: OAK-4725
> URL: https://issues.apache.org/jira/browse/OAK-4725
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: upgrade
> Reporter: Chetan Mehrotra
> Assignee: Tomek Rękawek
> Priority: Minor
> Fix For: 1.6, 1.5.10
>
>
> Currently in {{MigrationOptions}} in upgrade code the mmap option is only enabled if explicitly enabled.
> Given it provides much better migration speed it would be better to enable it by default (at least for non windows platforms) and provide a way to disable it by option. This would ensure that migration uses most suitable options per default
