Thomas Mueller commented on OAK-2163:
-------------------------------------
Revision 1629634 (trunk)
Revision 1629635 (1.0 branch)
Now a system property "tar.memoryMapped" is supported. If set, then memory
mapped files are used if possible. Usage:
{noformat}
java -Dtar.memoryMapped=true oak-run*.jar ...
{noformat}
> Oak-run "checkpoint" and "backup" don't use memory mapped files

> Oak-run, with the tar storage, explicitly disables using memory mapped files
> ("new FileStore(,, false)". It looks like this can result in out of memory.
