## How to do it?
There are two tricks:
* Configure to store small values in filer store. E.g., `weed filer -cacheToFilerLimit=1024` will store values less than 1KB to filer itself.
* Configure for [[Super Large Directories]]
This way, values less than 1KB is basically the same as the underlying key-value store, while the larger values are physically stored on volume servers, reducing the storage load.
* Configure to store small values in filer store. E.g., `weed filer -cacheToFilerLimit=1024` will store values less than 1KB to filer store itself. Accessing these entries are basically no difference than accessing the underlying key-value stores directly.
* Configure for [[Super Large Directories]]. It will avoid the additional work to maintain the file list in the large folder.
With the larger values offloaded, the underlying key-value store will also perform better with less bytes to move around.
