Speed up Datastore GC process

Hi All,

I came across a line which said "The datastore GC can be made to run faster by loading the index*.tar file into memory, reducing the number of “junk” nodes, and running the datastore GC without delay."

But could not understand what exactly it means. Any thought on this will be helpful.

The line you are quoting is from this blog: "https://umalbhole.wordpress.com/tag/garbage-collection/" as it is not an adobe blog, you would really need to ask the author what he means.

As far as Adobe documentation goes, you can find details here on loading the index in memory: http://docs.adobe.com/docs/en/cq/5-6-1/core/administering/persistence_managers.html#Configuring%20th...

"IndexInMemory  Boolean flag for making the repository read all TarPM index files entirely in memory. This can significantly boost performance for large repositories, but requires gigabytes of free RAM."

"Cache the Tar PM index" is also mentioned in the "Performance tuning tips for AEM 5.x" https://helpx.adobe.com/experience-manager/kb/performancetuningtips.html
