Number of files per folder/node

[#1]

I know that in past versions of CQ DAM /AEM Assets, there was a limit on how many files (images/PDFs) could be stored in an individual folder before system performance was impacted (I believe it was recommended no more than 500 files per folder).  In version 6.3, has this limit been increased? if so, what is the realistic limit of how many files per folder in v6.3?

This should serve as guideline Assets Sizing Guide to start with. Although usually  ordered folder does have the performance overhead and should be < 1000 assets as a general high level best practice. For larger numbers suggest unordered folders only. OAK recommends to use *un-orderable* node type to scale large number of child nodes [1].  In AEM Asset  its translate to use sling:Folder node type instead of sling:orderedFolder.

I believe it should be direct relative to the number of files and the Storage Size of files and your hardware/network to some extent.

1. If you have smaller files in size you can have them more, however if you want to search then it would create problem and traverse lot

2. If you have bigger files in size you should keep lesser number ideally as Network and IO cost would be more on any operations run that will lead to performance issues.
